深埋水电隧道TBM施工中的软岩变形分析

Analysis of Soft Rock Deformation During the Construction of Deep Hydropower Tunnel by TBM

通过对山西省引黄工程联接段7#隧洞TBM施工中掘进机被箍及相应区段部分衬砌片出现裂缝的事故分析及测试,得出软岩变形速率对深埋隧道TBM施工影响很大的结论,相应采取的处理措施证明是有效合理的。

This paper educes the conclusion that soft rock deformation rate influence greatly the construction of the depth Tunnel TBM, having adopted corresponding treating measure is effective and reasonable, by the accident analysis and lest which of the TBM was hoped and the relevant section tube piece brought cracks in the construction by TBM of 7^# Tunnel of the connection Works, YRDP.
