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...
