前言最初设计加筋土挡墙采用古典的土压理论,是将面板后侧和加筋区后部所作用的土压力假定按主动土压力的形式分布。自从把加筋体看成重力式墙后,侧向土压推动了墙背,因而改变了面板中的垂直与水平应力。这种称为后联式(tieback)的设计法假设墙绕其趾部向外转动,且土体破 Preface The original design of reinforced earth retaining wall using classical theory of earth pressure is to assume that the earth pressure acting on the rear of the panel and the rear of the stiffened zone is distributed in the form of active earth pressure. Since the stiffened body was considered as a gravity wall, lateral earth pressure pushed the back of the wall, thus changing the vertical and horizontal stresses in the panel. This design known as tieback (tieback) assumes that the wall rotates around its toe and that the soil is broken
