摘要
根据土体动态应力-应变关系及其推广的Masing加卸载准则,将增量法与场地地震线性反应解析解相结合,对剪切模量是其深度的某一指数函数的非均质地基,提出了地基非线性地震反应的半解析时域算法。算例结果表明,该算法是合理可行的。
Based on the relationship of soil body dynamic stress-strain and the extension of masing unloading and loading Rules and in combining the incremental method with the linear reaction analysis of the sesmic field, this paper suggests the semi-analysis time-region algorithm for the foundation non-linear seismic response to solve the ununiformity foundation with exponential function shear modules varying with the depth. The results of the calculation examples indicate that this algorithm is rational and feasible.
