摘要
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。
The article brings forward the design concept of building tunnels though active fault region with portals located in regions with less possibility of secondary disaster under the condition of the fixed alignment of ChengduLanzhou railway by summarizing the cases of railway encounter regional fault and analyzing the possible impact of active fault on railway engineering.
