根据隧道地质的实际情况,对某隧道坍方过程进行了数值分析,分析该特殊地质地段隧道坍方的发生、发展及破坏过程,探讨了隧道坍方的内在原因,说明了倒V形泥质夹层是隧道坍方的主要影响因素,并提出了有效的处治措施。
According to the actual conditions of the tunnel, the tunnel collapse process is numerically analyzed, and the occurrence, development and failure process of the tunnel collapse are analyzed. The intrinsic causes of the tunnel collapse are discussed. The inverted V-shaped muddy interlayer is the tunnel Collapse of the main factors, and put forward effective measures to deal with.
