地基沉降计算中压缩层厚度确定方法的比较
摘要:地基沉降计算中压缩层厚度确定方法主要有应变控制法和应力控制法两种。按这两种方法计算地基沉降,经比较可看出按应变控制法来确定压缩层厚度是不太合理的,其原因是由于按应变控制法确定的压缩层厚度与基底附加应力大小无关。最后给出了确定压缩层厚度方法的建议。
Abstract:There are mainly two methods to determine compressed layer thickness in calculating foundation settlements,control strain method and control stress method.Through comparing results of foundation settlement calculated by using the two methods,it is found that control strain method is not reasonable in determining compressed layer.And it resulted from the reason that the thickness of compressed layer determined by control strain does not put relationship with additional stress under foundation.The method to determine the thickness of compressed layer is suggested.
