摘要
现行复合地基沉降理论 ,是基于桩土变形一致的刚性基础下的复合地基建立的 ,在桩土变形不一致的柔性基础下 (如公路地基 )应用时 ,误差很大。将模型试验成果及实际工程的实测值与理论计算值进行了比较 ,分析误差及原因 。
The composite subgrade settlement theory in effect is based upon that the deformation of foundation and piles under a rigid foundatio n is identical. If it is not the case (as flexible subgrade in highway) its erro r is considerable. In this paper, through comparison between the theoretical and practic al values obtained from model tests and enqinering practic. The case of error i s analysed and remedy is discussed.
