摘要
本文从微单元上层力学平衡的角度,推求出直线破裂面时被动土压力的大小和分布问题,论证了其分布的非线性性质。对于库仑理论在概念和使用上进行了拓广,有一定实用性。
n this paper, based on the balance of micro unit. the formulas of the magmitude of the passive earth pressre and its distribution are carried out according to linea failuresurface. So the non-linea property of passive earth pressure is clearly pointed out.Coulomb's theory is widened here successfully. The method used here is useful and practical.
