摘　　要：以某市政结构顶管工程为主要研究对象,分析市政工程顶管施工中的沉井结构优化设计。在此基础上,从沉井壁厚设计、顶力计算、环向计算以及竖向抗拉计算等方面着手,介绍了沉井结构优化设计的内容,并对其施工方法及应当注意的问题进行了总结。This paper takes a municipal structure pipe jacking project as the main research object, analyzes the optimization design of caisson structure in the pipe jacking construction of municipal engineering. On this basis, the optimization design of caisson structure is introduced from the aspects of sinking wall thickness design, jacking force calculation, circumferential calculation and vertical tensile calculation, and summarizes the construction method and the problems that should be paid attention to.

关 键 词：市政工程 顶管施工 沉井结构 优化设计
