Based on Duncan-Chang model and result of experiments,formulas to calculate tangent elastic modulus were developed for lateral unloading and loading conditions.
分析认为,基坑支护外侧的土体有可能产生侧向卸载和加载两种应力路径,因此进行了侧向卸载、加载的应力路径试验,并根据邓肯-张模型的思路和试验结果,推导了侧向卸载、加载的切线弹性模量公式。

The power function relationship of original shear modulus versus embedded depth to account,time scaling factor of input earthquake wave on shaking board were determined by similar resonant frequency,and acceleration amplitude factor of input wave was obtained by strength parameters(cohesion c and internal friction angle φ) of soils.
基于Mohr-Cou lomb破坏准则和双曲线动本构模型恢复力骨干曲线,提出在保持归一化的剪应变比一致条件下,兼顾振动性态和破坏相似的振动台模型实验相似律:由土体初始剪切模量随埋深的幂函数变化规律,按振动性态相似原则确定台面输入地震波波形的时间压缩比,再以岩土材料的强度参数(c,φ值)按破坏相似原则确定台面输入波形的幅值比,得到各主要物理量的相似律。
