摘要
在分析容重增加法基本原理和缺陷的基础上,提出容重增加法用于加筋土挡墙稳定性分析时的修正方法,给出容重增加法在FLAC3D中的实现步骤,并进行实例分析。研究结果表明:岩土体容重的增加会导致岩土体力抗剪强度的增大和筋材的抗拔力增加,其应用于加筋土挡墙稳定性分析时应进行必要的修正,证明提出的修正方法是可行且高效的。
The basic principle and defects of gravity increase method were analyzed, and the correction method for theT gravity increase method that used for reinforced earth retaining wall stability analysis was put forward. Its implementation steps in FLAC3D was given, and an example was analyzed. The results show that the increase of rock and soil bulk density leads to the increase of the geotechnical strength shear strength and the strength reinforcements of anti - pullout. But it is should be modified when the gravity increase method is applied to the analysis of reinforced soil retaining wall stability. Besides, the correction method is feasible and efficient.
