西铁车2号隧道塌方处治技术

Collapse Treatment Technology of the Xitieche No.2 Tunnel

隧道施工过程中,实际地质与原设计地质不符在所难免,因此,需要通过变更设计解决施工问题,而实际施工时由于变更设计不及时、不到位或初期支护质量不合格极易造成塌方事故。本文通过介绍山西中南部铁路通道西铁车2号隧道先后两次塌方经过、原因分析和处理措施,旨在总结经验和教训,从而避免今后类似事故的发生。

In the process of tunnel construction,the actual geology and original design of geology are not matched inevitably,therefore,we need to change design to solve the construction problem. Collapse accident is extremely easy to be caused in the actual construction due to the design changed not in time and inadequately,or unqualified quality of initial support. Through introduction of the twice course of collapse,cause analysis and treatment measures of the south-central Shanxi Railway Xitieche No. 2 Tunnel,it aims at summing up experiences and lessons,so as to avoid the occurrence of similar accidents in the future.
