山岭重丘区公路隧道震害及震后修复方法研究

摘要

介绍了山岭重丘区公路隧道常见的震害类型,分析了地震作用下发生隧道破坏的原因,结合实践经验,从外部地质、洞口段、洞身段等方面入手,提出了针对性的震后修复措施,可有效解决公路隧道的震害问题.%The paper introduces common mountainous highway tunnel seismic disasters types,and analyzes tunnel seismic damage causes. Com-bing with experience,starting from aspects of external geology,entrance section and tunnel body,it puts forward corresponding seismic mainte-nance measures,which will effectively solve highway tunnel seismic disasters.
