摘　　要：随着顶管沉井在市政供热顶管工程得到普遍应用,沉井(也叫工作井)结构设计的合理与否直接影响整个顶管工程的安全与质量,从而决定整个供热管网的质量安全。从尺寸、承载力、构造等方面系统地对矩形工作井的设计过程进行了详细介绍,对广大设计人员进行工作井结构设计具有一定的参考价值。With the widespread application of pipe jacking and sinking wells in municipal heating pipe jacking projects,the reasonable design of the working shaft structure directly affects the safety and quality of the entire pipe jacking project,which determines the quality and safety of the entire heating network.This article provides a detailed introduction to the design process of rectangular working shaft from the aspects of size,bearing capacity,and structure,in order to provide reference for designers when designing working shaft structures.

关 键 词：市政供热 顶管设计 矩形工作井
