摘要
本文通过对野外十字板强度进行数理统计 ,回归出土壤的强度指标。并用这一指标来计算土坡的安全系数 ,从而避免了用土体各方向中强度最小的竖向剪切面上的抗剪强度来计算安全系数导致求得的安全系数偏小的问题 ,并考虑了固结度的影响。详细介绍了用十字板强度回归土壤强度指标的理论、方法和公式。最后附有用本文所介绍的方法计算了若干项实际工程的安全系数 。
By making mathematical statistics on the field vane strength,the strength index of soil has been regressed,which was used to calculate the safety factor of soil slope By so doing,it was avoided to use the shear strength in the vertical shear plane of the least strength in various directions of the soil mass to calculate the factor of safety to result in a lower safety factor The influence of consolidation degree was considered when the strength index of soil was used to calculate safety factor The paper expounds the theory,methods and equations for regressing the vane shear strength to the strength index of soil The paper also presents a few engineering cases for which the method given in the paper was used to calculate the factor of safety so as to illustrate the practical use of the method in engineering practice
