| 摘 要： | 从常规三轴压缩试验得到横观各向同性土层的力学参数，综合9种来自于不同国家和地区的横观各向同性土层的土样参数，研究分析了横观各向同性土层参数对建筑物沉降的影响。作为典型例子，对上海一幢剪力墙结构的箱形基础与横观各向同性土进行共同作用分析，并与各向同性土层上的分析结果进行比较，结果表明：横观各向同性土层参数对沉降的影响有些不同，尤其是不排水加载条件确定的土层参数影响的结果大不相同。

| Abstract: | The parameters of transversely isotropic soil are obtained from the conventional triaxial compression tests.In order to study the effect of transversely isotropic soil parameters on settlements of buildings,nine types of transversely isotropic soils taken from different countries are used.As a typical example,the interaction analysis of cross-wall structure and box foundation on transversely isotropic soil has been made and compared with the results on isotropic soil.In this example the structure is analyzed by using the double extended substructure(finite element) method and the transversely isotropic soil by the finite layer(element) method.The results show that the effect of transversely isotropic soil on settlement is somewhat different,especially for the soil parameters determined by the consolidated-undrained tests.It is expected that these conclusions are useful to the foundation designers. |
