摘　　要：基于运用工程边坡的实测资料反算强度参数的目的,改变了瑞典法安全系数的表达公式,使其适用于较均质的土质或类土质边坡的参数反算。通过反算粤赣高速公路一个不稳定边坡的实测资料,得到了不稳定体的强度参数,通过分析反算过程的误差传递规律,给出了计算结果的误差范围。计算结果表明,反算需要的条件不高,得到的强度参数符合工程实际,对于校核勘察结果和试验数据,修订边坡设计具有实际意义。In order to back analyze the strength parameters and through measured materials of engineering slopes, the expression formula of Swedish method is changed to make it to suitably back analyze the parameters of relative homogenous or analogous soil slopes. The strength parameters of an unstable body are got by back analyzing measure material of one slope of Yue-Gan Expressway,and the error range of computational results is given by analyzing the error-transfer rule on the process of back analysis. Computational results show that back analysis needs low condition and has practical meaning for checking the survey results,testing data,and correcting the slope design.
