Inclined-straight alternating group piles-soil-structure interaction experiment model

Abstract

The invention discloses an inclined-straight alternating group piles-soil-structure interaction experiment model, belongs to the technical field of geotechnical similar simulation experiments with an aim to solve problems that the inclined-straight alternating group piles-soil-structure interaction experiment model is complex in manufacturing. The inclined-straight alternating group piles-soil-structure interaction experiment model is composed of a soil box, foundation soil, an inclined-straight alternating group pile foundation, a bearing platform and an upper portion structure; the soil box is of a hollow cuboid body provided with an upper opening and is formed by welding of steel plates; the foundation is divided into two layers, the upper layer is clay, and the lower layer is sandy soil; the inclined-straight alternating group pile foundation is formed by two vertical piles and two inclined piles, and pile bottoms are identical in elevation; the bearing platform is a cuboid body cast with concrete, and the vertical piles and the inclined piles are integrally connected through the bearing platform; the upper portion structure is composed of a single-column pier and a counter weight, the single-column pier is of a cylindrical body, two vertically-arrayed threaded rods are embedded in the upper end of the single-column pier, and the counter weight is formed by combination of weights different in weight. The inclined-straight alternating group piles-soil-structure interaction experiment model is simple in structure, convenient to machine and manufacture and high in engineering practicability.

Description

technical field [0001] The invention belongs to the technical field of geotechnical similarity simulation experiments, in particular to a similarity simulation experiment model, in particular to an oblique-vertical alternating pile group-soil-structure interaction experiment model. Background technique [0002] At present, inclined and straight alternating pile groups are widely used in highway bridges, port terminals, offshore drilling platforms, high fill embankments, high tower structures, super high-rise buildings, foundation pit support, foundation treatment, large transmission line towers and airports, sports In the foundation of public buildings with long-span roof structures such as venues, cultural and sports activity centers, and exhibition halls. Although some experimental studies on pile-soil-structure dynamic interaction models have been carried out at home and abroad in recent years, and many research results have been obtained, but these studies are all for ve...

AI Technical Summary

Problems solved by technology

[0003] In order to study the force and deformation characteristics of the inclined-vertical alternating pile group-soil-structure interaction system, under the support of the National Natural Science Foundation of China (No. The experimental model of alternating pile group-soil-structure interaction is complicated, so that there is still a lack of matching similar simulation experimental models. Therefore, it is necessary to invent an effective experimental model of inclined and vertical alternating pile group-soil-structure interaction
