摘要

以瑞典条分法为例，用流网的性质来确定土条边界上的静水压力，证明了渗透压力（或动水压力）与土条中的水重和周边静水压力是一对平衡力，澄清了对此问题的模糊认识，简化了计算方法。将其应用到不平衡推力法的公式推导中，通过分析，找到了目前规范方法中剩余推力偏大的内在原因，并结合算例进行了分析。

Abstract

Based on the example of Sweden slice method

defined the boundary water pressure utilizing the flow nets property

it is proved that the seepage force is equilibrant with the water weight and the water pressure around the vertical slice

clarified the mistiness knowledge

simplified the calculation methods

deduced the formula of imbalance force method using seepage force

found out the inhesion reason that the imbalance force is large than normal

and analyzed by practical examples.
