圆形地下连续墙顶管工作井施工阶段和顶进阶段的内力计算与设计

Computation of Internal Forces and Design for Circular Diaphragm Wall Shaft of Jacking Pipe Project in Excavating Stage and Driving Stage

本文针对采用地下墙技术建造的圆形顶管工作井,提出了工作井的结构设计方案,建立了施工阶段圆形地下墙槽段和底板的计算方法、顶进阶段工作井的稳定性验算方法,以及墙身的环向内力、竖向内力的计算方法。

For a cylindrical structure, as a working shaft of jacking pipe project constructed by diaphragm wall technigue, this paper offers a design plan‘ establishes a series of computation methods for the curved panel and bottom plate in construction stage,stability of the shaft, internal forces of the panel in vertical and circular directions.
