验算挡土墙稳定性的平衡推力法
摘要:迄今一直得到广泛应用的挡土墙稳定性验算方法存在几个问题,将作用力的分力割裂为两个作用力进行稳定性验算违背力学原理,定义本身的局限及地基软硬程度的差异使抗倾覆稳定系数具有不确定性并且与基底合力偏心矩的作用重复,验算时采用主动土压力或忽略被动土压力的作用造成地基的承载力偏低。对存在的问题加以改进后提出了验算挡土墙稳定性的平衡推力法。
Abstract:There are several problems in stability calculation method of retaining wall which has been widely used.The problems are:estimating the stability doesn't comply with the principles of mechanics by separating the components of acting force into two acting forces; the anti-overturning stability coefficent is uncertain due to the defects in its definition and the differences of the foundation's hardness,and repetitive with the linear eccentricity of the basement's join-force;it would cause the insufficient foundation bearing capacity that the active earth pressure is be used or the passive earth pressure is ignored.the balance thrust method is put forward so as to improve the stability calculation method of retaining wall in view of the existing problems.
