朗肯(Rankine)和库仑(Coulomb)土压力理论在工程中应用较多,但由于它们都是建立在一定理想化假设条件下,与实际土体都存在着一定的差异性。因此,两种方法何时准确,何时误差较大,需要进行探讨。本文根据一个算例就其进行讨论。 Landine Rankine and Coulomb earth pressure theory are widely used in engineering, but because they are all based on some idealized assumptions, they have some differences from the actual soil. Therefore, when the two methods are accurate and when the error is large, we need to explore. This article discusses it based on a study.
