条分法中土条周边水压力与渗透力之间的关系
摘要:目前在边坡稳定分析中,常常存在土条周边水压力与渗透力同时考虑的现象,导致水压力的重复考虑。针对这个问题,以瑞典条分法为例,通过用流网性质来确定土条周边水压力的方法,研究了条分法中土条周边水压力与渗透力之间的关系,得出了渗透力与土条中的水重和周边静水压力是一对平衡力的结论,澄清了模糊认识,纠正了计算方法。
Abstract:The seepage force and the water pressure force is considered simultanously in the slope stability analysis every so often at present, which causes the water pressure force is double calculated. Based on the example of Sweden slice method, defined the water pressure around the slice utilizing the flow nets property. It is proved that the seepage force is equilibrant to the water weight and the water pressure around the slice, clarified the mistiness knowledge, and corrected the calculation methods.
