Model device for remolding soft soil pile-supported embankment under cyclic load effect and test method
The invention discloses a device and a test method for remodeling a soft soil pile-supported low embankment model under the cyclic load effect. The model device comprises a vertical cyclic load loading assembly, an embankment assembly and a remolded soft soil rigid pile foundation from top to bottom. The vertical cyclic load loading assembly is connected with the model device by adopting a horizontal variable cross-section frame beam, the loading is driven by an electric cylinder, and the height can be freely adjusted up and down; the embankment assembly is used for simulating a prototype embankment, and a geogrid is arranged at the bottom of the embankment; the remolded soft soil rigid pile foundation comprises remolded soft soil, a rigid pile, a pile cap and a drainage sand layer. The test method comprises the steps of test design, remolded soft soil rigid pile foundation manufacturing, embankment assembly manufacturing, static load testing, cyclic load testing and data processing. The device is used for a large-scale pile-supported low-embankment model test under cyclic load, and systematic research can be carried out on soil arching effect evolution, a load transmission mechanism, soft soil foundation consolidation and long-term accumulated deformation under the action of traffic load in the pile-supported low-embankment.
本申请公开了循环荷载作用下重塑软土桩承式低路堤模型装置及试验方法。该模型装置从上至下包括竖向循环荷载加载组件、路堤组件和重塑软土刚性桩地基。竖向循环荷载加载组件采用水平方向变截面框架梁与模型装置连接，加载采用电动缸驱动且上下可自由调节高度；路堤组件用于模拟原型路堤，在路堤底部设置土工格栅；重塑软土刚性桩地基包括重塑软土、刚性桩、桩帽和排水砂层。本试验方法包括试验设计、重塑软土刚性桩地基制作、路堤组件制作、静载试验、循环荷载试验和数据处理。该装置用于循环荷载下的大比例尺桩承式低路堤模型试验，可对桩承式低路堤中土拱效应演化、荷载传递机制、软土地基固结及交通荷载作用下长期累积变形开展系统性的研究。
