俯斜墙背条件下朗肯与库伦土压力理论的研究

Research on rankine’s earth pressure theory and coulomb’s earth pressure theory on overlook wall

摘要: 从挡土墙抗滑、抗倾覆安全系数和挡土墙的主动土压力两个角度,研究建立在朗肯土压力理论与库伦土压力理论基础上的不同主动土压力计算方法所带来的误差,认为在俯斜的挡土墙墙背条件下,应使用抗滑、抗倾覆安全系数来判断土压力计算方法是否合理.

Abstract: Great error may be induced by the different methods which are based on the Rankine's earth pressure theory and Coulomb's earth pressure theory. They are studied from two viewpoints of active earth pressure and resistive overturning safety factor or resistive sliding safety factor. And it is further considered that the safety factor is the best approach to study whether the method is correct.
