摘要
本文就软土震陷和砂土液化危害性分析中的三个问题进行了讨论,即具条形基础建筑物的有限元划分、土壤初始模量和静动应力不同的组合对计算震陷值的影响。文中指出,在震陷试验和计算中存在着测试误差和各种假定,但是,由于采用了修正系数,这些不合理性在一定程度上均得到了补偿。
In this paper, three influencing problems in the analysis of seismic settlement for clays and liquefaction hazard for sands, namely, the FEM mesh division of structure with strip foundation, the initial modulus of soils and the different combination of static and dynamic stresses are discussed. It is pointed out, finally, that although there must be some errors in the testing and calculation process due to various assumptions these unreasonable factors are all compensated in some extent because of the use of modification coefficients.
