摘要：

The counter-analysis on geotechnical parameter plays a very important role in accurate computation and forecast of foundation subsidence. But the existing soil-body non-linearity constructive model involves many computation parameters, which will cause difficulties or even errors to the parameter counter-analysis. This article intends to give an introduction to the principle of system sensitivity analysis, and take an actual project for an example to account for the sensitivity analysis method for calculation parameters in the E-v model and the E-B model. By this method, reasonable parameters of subsidence counter-analysis in E-v model and E-B model are determined, thus enhancing the efficiency of counter-analysis.
