摘要
针对考虑位移影响的土压力计算问题,采用正切函数对朗肯土压力理论进行改进,给出了一种新的考虑位移影响的土压力计算模型。算例表明推导的新公式较好地反应了挡土墙上土压力大小随其位移而变化的特性。
To dispose the problem such as earth pressure considering displacement, a new calculation model is given, in which the Rankine＇s earth pressure theory is improved by using the tanh function. From the example, the principle is reflected clearly that the earth pressure of retaining wall is changed with the change of displacement.
