摘　　要：以分层总和法结合改进的高木俊介方法作为实际施工时土体分级加载计算的正分析数学模型,用最小二乘法建立位移目标函数,通过单纯形法结合等参变换的优化处理方法,对真空联合堆载预压软基加固处理结合实例进行位移反分析研究。一方面对真空联合堆载预压的原理作进一步的分析研究,另一方面结合实际工程对塑料排水板+真空联合堆载预压的效果进行分析,以便进一步改进和更好地指导以后的现场施工。This article deals with the displacement back-analysis for the Vaccum-Heaped Load Combining Pre-compression (VHLCP),which employs the positive-analysis model based on the layerwise summation method combined with the modified GAOMUJUNJIE-Method,the displacement objective function constructed by the least square formulas,and the optimizing method of simplex. The twofold analysis of further study of the Vaccum-Heaped Load Combining Pre-compression theory on one hand and of its actual effects of the living example on the other hand will improve and better direct the field work.
