摘　　要：采用分层总和法计算基础沉降,对于复合地基,复合模量和修正系数难以取得,计算误差往往较大。该文利用载荷试验结果,结合分层总和法推算基础沉降,对于主要压缩层,无需取得复合模量和修正系数。经过工程验证,计算结果与实际较吻合,能够满足设计需要。For settlement of composite foundation,it is difficult to obtain the composite modulus and modified coefficient by layerwise summation method,and the computing error is often rather big.Based on the results of plate load test,the foundation settlement is solved by layerwise summation method,which does not need the composite modulus and modified coefficient for main compressed layers.Through verification by engineering practice,the computing results agree with the actual measured data,and it can meet the design requirements.
