Active Earth Pressure on Retaining Walls with Layered Cohesive Backfills and considering cracking Xiyan Jiang 1, a,Suwei Di1,b 1Hebei Institute of Architecture and Civil Engineering ,Zhang jiakou 075024 , China ajxyjhy@163.com, bdisuwei@126.com Keywords: Layered cohesive backfills ,Retaining wall , Active earth pressure .
Introduction The determination of the magnitude and distribution of earth pressure against rigid retaining wall is important in the design of civil engineering.
In practical engineering, the wall is often encountered in condition of layered backfills , so to carry out studies of this problem has some practical significance. active earth pressure on retaining walls with layered non-cohesive backfills is discussed from reference [3].
