摘要
从非饱和土的特性分析入手 ,论述现有膨胀土挡土墙上主动土压力的计算方法中存在的问题 ,在此基础上 ,提出根据库仑土压力理论 ,并考虑非饱和膨胀土基质吸力的土压力计算方法 ,推导相应的主动土压力计算公式 。
From the properties of unsaturated expansive soils, this paper has first discussed the shortcomings of present methods which are explored to calculate the active earth pressure on the retaining wall. Then a calculation formula is proposed based on the Coulumb earth pressure theory taking into account of the matric suctions of unsaturated soil. The example shows the relationship between the active earth pressure and the moisture of soils and the reasonability of the proposed method.
