Test method for simulating influence of soft and hard interbed bedrock on deformation and damage of pile foundation
The invention provides a test method for simulating the influence of soft and hard interbed bedrock on deformation and damage of a pile foundation. The method comprises the following steps: preparing a combined sample A for simulating soft and hard interbed bedrock and a comparison combined sample B for simulating hard bed rock through a mold, and carrying out a loading test on model piles in the combined sample A and the comparison combined sample B in a graded loading manner; axial stress-axial displacement relation curves of the model piles in the two combined samples are drawn according to test results, the two groups of test curves are drawn in the same coordinate system to obtain a comparison curve graph of the two groups of tests, and a theoretical basis is provided for later optimization of the pile length in soft and hard interbedded bedrock by observing the relation between the two groups of curves. According to the method, an existing triaxial compression testing machine is utilized, a combined sample is adopted to simulate the influence of soft and hard interbed bedrock on the pile foundation, and a test comparison result serves as a reference basis for pile foundation length optimization.
本发明提供了一种模拟软硬互层基岩对桩基变形破坏影响的试验方法。所述方法包括：通过模具制备出模拟软硬互层基岩的组合试样A和模拟硬层基岩的对比组合试样B，并对组合试样A和对比组合试样B中的模型桩进行加载试验，加载方式采用分级加载；根据试验结果画出两个组合试样中模型桩轴向应力‑轴向位移关系曲线，并将两组试验曲线画在同一坐标系中得到两组试验的对比曲线图，通过观察两组曲线之间关系，为后期软硬互层基岩中桩长优化提供理论依据。本发明利用既有的三轴压缩试验机，采用组合试样模拟软硬互层基岩对桩基的影响，通过试验对比结果为桩基长度优化做参考依据。
