滇中引水输水隧洞过活动断裂带结构变形破坏规律
Structural Deformation and Failure Law of Active Fault Zone in Transmission Tunnel of Yunnan Dianzhong Water Diversion Engineering
摘要
Abstract
In order to study the deformation and failure laws of the structure of the water diversion tunnel passing through the active fault zone in central Yunnan,this paper takesXianglushan Tunnel passing through Heqing-Eryuan fault zone as an example and conducts an analysis of the impact of creep and sliding of the active fault on the safety of the tunnel structure under two conditions:without and with anti fracture measures.It obtained the deformation distribution characteristics,failure modes,and damage evolution laws of tunnel lining structures under creep and sliding under two different conditions.The research results indicate that setting up connecting sections helps to disperse the influence of creep and displacement of active fault zones on lining structures,ensuring the safety of tunnel structures.关键词
