Background technology
Pile foundation is to have obtained extensive use in the engineerings such as building, water conservancy.In recent years antislide pile as a kind of reinforcement means commonly used in the landslide control of reality, brought into play important function (Xiong Chaohui. dark Shan speedway 101 landslide regulation new technologies-garden peace antislide pile open cut tunnel [J]. rock mechanics and engineering journal; 2001,20 (4): 532 – 537.; Liu Xinrong, Liang Ninghui, gold state, etc. progress and the application [J] of antislide pile in slope project. Chinese geological disaster and control journal, 2006,17 (1): 56 – 62.).At present, obtained many progress at the aspects such as design and calculation method of antislide pile reinforcing side slope, but still lack can reasonable consideration antislide pile reinforcement mechanism the assay method.Be necessary to further investigate the deformation and failure mechanism of antislide pile reinforcing side slope under the different loading conditions, disclose the interaction mechanism and the rule of antislide pile and its surrounding soil.Centrifugal model test is one of research means of geotechnical engineering, at home and abroad by extensive employing, like BRANDENBERG S J; BOULANGER R W, KUTTER B L, et al.Behavior of pile foundations in laterally spreading ground during centrifuge tests [J] .Journal of Geotechnical and Geoenvironmental Engineering; 2005; 131 (11): 1378 – 1391., ABDOUN T, DOBRY R, O ' ROURKE T D; Et al.Pile response to lateral spreads:centrifuge modeling [J] .Journal of Geotechnical and Geoenvironmental Engineering; 2003,129 (10): 869-878. and Yu Yuzhen, Deng Lijun. antislide pile reinforcing side slope seismic response centrifugal model test [J]. the geotechnical engineering journal; 2007,29 (9): 1320 – 1323..The feasible simulation of antislide pile in centrifugal model test is an important problem; Especially at the different failure modes of reproducing reinforced soil slopes and the aspects such as selection of reinforcement material; Need carry out rationally abstract and then promote research, for the consolidation effect of rational evaluation antislide pile provides the basis the reinforced soil slopes failure mechanism.
For antislide pile, bear in the process of all kinds of loads in side slope, mainly bring into play tension and shear strength, to side slope drag is provided, stop the generation of slip-crack surface, the pattern that ruggedized construction takes place to destroy mainly is that tension is destroyed and shearing resistance destroys.Mostly the selection of existing Model Pile is the homogeneous material that certain is confirmed, such as various metals etc., the tension of these materials and shear strength are generally all fixed, and under definite side slope condition, its failure mode also is certain.The selection of existing Model Pile can't comprehensively reflect influence, especially the shear failure pattern of all kinds of intensity of stake to its failure mode, is difficult to consolidation effect is carried out thoroughly evaluating and then realizes the ruggedized construction better choice.
Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the object of the present invention is to provide a kind of shear constitution Model Pile that is used for model testing, can implementation model the simulation of the shear failure pattern of the varying strength of Model Pile in the test; Principle is simple, and control is convenient; Cost is low; Can promote the research of novel stake.
To achieve these goals, the technical scheme of the present invention's employing is:
A kind of shear constitution Model Pile that is used for model testing; By a plurality of shear constitution modules 1 in order interlock constitute; The cross section of each shear constitution module 1 is shaped as main body with I-shaped, and following horizontal edge 2 two ends in the I-shaped shape connect vertical edge 4 respectively downwards, and the termination of each vertical edge 4 all has inside laterally separated retaining 3; The length of the last horizontal edge 5 in the I-shaped shape is consistent with the spacing of two vertical edges 4, and the last horizontal edge 5 of shear constitution module 1 is inserted between two vertical edges 4 of adjacent block and realizes interlock.
Realize after the interlock; Be provided with cylindrical roller 6 between the following horizontal edge 2 of last horizontal edge 5 and adjacent block; The length direction of cylindrical roller 6 is vertical with last horizontal edge 5 length directions; Two of last horizontal edge 5 and adjacent block laterally all are provided with ball roller bearing 7 between retaining 3, the contact surface between the adjacent block is used glue.
Compared with prior art; The present invention by the module of certain length of side (like 1cm) through structure interlock and bonding forming; Can select different block sizes according to the research needs, connect aluminium block to any length, formation has the pilework that shear breakage can take place for several.Carry out bonding through glue between each block of the present invention; Adopt different bonding thickness can reach different intensity with adhesives; Make Model Pile have different shear strengths; Select suitable adhesives to form and have the seriation Model Pile of varying strength, can adjust in test the intensity of stake arbitrarily, realize the simulation of shear failure pattern and the consolidation effect of research piles with different.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is explained further details.
As shown in Figure 1, the present invention is a kind of shear constitution Model Pile that is used for model testing, by a plurality of shear constitution modules 1 in order interlock constitute, each shear constitution module 1 material is an aluminium, package size is decided as required.The cross section of shear constitution module 1 is shaped as main body with I-shaped; Following horizontal edge 2 two ends in the I-shaped shape connect vertical edge 4 respectively downwards; The termination of each vertical edge 4 all has inside laterally separated retaining 3; The length of the last horizontal edge 5 in the I-shaped shape is consistent with the spacing of two vertical edges 4, and the last horizontal edge 5 of shear constitution module 1 is inserted between two vertical edges 4 of adjacent block and realizes interlock, after realizing interlock; Be provided with and the vertical cylindrical roller 6 of last horizontal edge 5 length directions between the following horizontal edge 2 of last horizontal edge 5 and adjacent block, two of last horizontal edge 5 and adjacent block laterally all are provided with ball roller bearing 7 between retaining 3.
The structure of cylindrical roller 6 is on cuboid 61, to laterally arrange cylinder 62 and form as shown in Figures 2 and 3, and wherein cylinder 62 can roll.
The structure of ball roller bearing 7 such as Fig. 4 and shown in Figure 5 are on rectangular 71, to leave some spherical pores 72, then ball 73 are installed in spherical pore 72 and are constituted, and wherein ball 73 can roll in spherical pore 72.
Each space is filled up the back structure by roller bearing and will can not be occured bending and deformation basically; And can only relatively move along the roller bearing direction, the contact surface between the adjacent block is used glue, makes structure have certain shear strength; The different glue of main employing carries out bonding in the test; After stake reaches shear strength, will form the shear failure pattern of stake in the test along bonding plane generation slippage.
Because the shape of each module is identical, therefore link block is to any length as required, and formation has the pilework that shear breakage can take place for several.
