Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, the present invention is a shear structure model pile used for model tests, which is composed of a plurality of shear structure modules 1 sequentially occluded, each shear structure module 1 is made of aluminum, and the assembly size is determined according to needs. The cross-section of the shear structure module 1 is mainly in the shape of an I-shape. Block 3, the length of the upper horizontal side 5 in the I-shaped shape is consistent with the distance between the two vertical sides 4, and the upper horizontal side 5 of the shear structure module 1 is inserted between the two vertical sides 4 of the adjacent module to achieve engagement. After the occlusion is realized, a cylindrical roller 6 perpendicular to the length direction of the upper transverse edge 5 is arranged between the upper transverse edge...

Abstract

A model pile in shear structure for model testing is formed by a plurality of shear structure modules which are sequentially meshed. The cross section of each shear structure module is mainly H-shaped. Two ends of the lower transverse edge of the H shape are respectively downwardly connected with a vertical edge, and one end of each vertical edge is provided with an inward transverse retainer. The length of the upper transverse edge of the H shape is equal to the distance between the two vertical edges. The upper transverse edges of the shear structure modules are inserted between the two vertical edges of two adjacent modules and to be meshed. According research needs, the modules different in size can be selected to be connected in any length to form a plurality of pile structures capable of forming shear damaging surfaces, and the pile structures can be adhered to form serialized model piles different in strength by selecting proper adhesives, the strength proportion of the piles can be optionally adjusted in testing, simulation of a shear damaging mode can be realized, and reinforcing effect of the different piles can be researched.

Description

technical field [0001] The invention relates to the technical field of pile foundation model tests in slopes and foundations in civil and water conservancy projects, in particular to a shear structure model pile used for model tests. Background technique [0002] Pile foundation is widely used in civil engineering, water conservancy and other projects. In recent years, anti-slide piles have played an important role in the actual landslide control as a commonly used reinforcement method (Xiong Chaohui. New technology for landslide control of Shenshan Expressway 101-Yuan'an anti-slide pile open hole[J]. Rock Mechanics and Engineering Acta Sinica, 2001,20(4):532–537.; Liu Xinrong, Liang Ninghui, Huang Jinuo, etc. Research progress and application of anti-slide piles in slope engineering [J]. Chinese Journal of Geological Hazards and Prevention, 2006, 17 (1):56–62.). At present, a lot of progress has been made in the design and calculation methods of anti-slide piles to streng...
