中文摘要:地铁施工中一般采取先竖井继而横通道后开马头门进行正线施工的施工工序。广州轨道交通五号线广州火车站站竖井的开挖方案将原设计优化为在竖井下扩大直接开马头门，在确保结构稳定的同时缩短了工期，减少了二衬背后回填混凝土。

Construction and Optimization Design for Subway Shaft Excavation
Abstract:The general procedures for constructing subway are as follows: first excavate the shaft, then horizontal pass, finally ingate. The original design for the shaft excavation in Subway Station at Guangzhou Railway Station of Track Traffic Line 5 of Guangzhou was optimized to directly open the ingate by enlarging the lower section of shaft. The time limit for the project was shortened meanwhile the stability of the structure was ensured. The backfill concrete volume after second liner was reduced. That can be used for reference by similar project.
