摘要
预测和控制顶管施工引起的土层变形是城市环境土工学的一个重要研究课题。采用理论与经验相结合的方法,考虑施工应力引起的土体位移,对顶管施工引起地面横向沉降的经典理论方法Peck地面沉降槽理论公式进行了修正,使之更加符合工程实际。并通过工程实例进行了验证。
The prediction and control of ground deformation have become one of the main research subjects.In this dissertation,according to the basic theories and the experiences,a strict research was carried on soft body's dis- placement caused by construction stress.Peck's formula of ground deformation trough theory was amended to more fit realities of the projects.This method has been tested by practice of some projects.
