通过对铁路建设中遭遇区域性大断裂时典型案例的总结,活动断裂对铁路工程可能产生破坏的分析,在拟建的成兰铁路走向不能调整的情况下,提出原则上以隧道通过活动断裂区,隧道不与活动断裂相交,将洞口设在地震诱发的次生灾害发生可能较小的区域的设计思路。 Through the summary of the typical case of regional major faults in the railway construction and the analysis of the possible rupture of the railway project caused by the active fracture, under the condition that the planned direction of the Chenglan Railway can not be adjusted, it is proposed that in principle, the tunnel should pass through the active fault zone , The tunnel does not intersect with the active fault, and the hole is located in the area where the earthquake-induced secondary disaster may occur.
