Abstract

The invention provides a visualized test device and method for calculating the width of a model pile. The device is mainly composed of a model box, model soil, the model pile, a high-speed particle camera, a bolt, a fastener, a steel rod and displacement marks; and the model box is a transparent box body composed of a steel structure and acrylic, the model soil has similar physical and mechanicalindexes with prototype soil, and the model soil and the model pile are distributed in the model box. The displacement marks are distributed on the surface of the model soil at a certain angle, the bolt and the fastener cooperate with the steel rod to form a mini scaffold used for erecting detection equipment, and the high-speed particle camera is erected right above the model soil body. Compared with an existing test device and test method, overlapping of the visualized test device and method for calculating the width of the model pile is convenient and flexible, stress diffusion of the soil body can be quantitatively analyzed according to a similar principle, the calculated width of the pile body is obtained by calculating, and the visualized test device and method for calculating the width of the model pile can be widely used in the study of pile-soil interaction under different site slopes, soil properties or geometric dimensions of pile bodies.

Description

Technical field

[0001] The invention belongs to the technical field of geotechnical engineering and geological engineering, and relates to a model test device and a test method, in particular to a visual test device and a test method for calculating the width of a model pile. Background technique

[0002] my country has a vast territory and complex engineering geological conditions. Different site conditions put forward different requirements for the foundations of its structures. Especially in southwest China, slope sites account for about 90% of the land area. In engineering construction fields such as roads, railways, construction, electricity, water conservancy, etc., it is often necessary to set up structures on adjacent slopes or slope sites. Due to the site topography and other reasons, there are many cases of instability of the pile foundation of the slope site due to insufficient horizontal bearing capacity. The design index of its horizontal bearing capacity, such as th...
