摘要
头道穴隧道是怀丰公路的重点工程。针对其周围地质条件复杂而造成明洞段偏压的情况,考虑到工程设置偏压挡土墙等施工特点,采用荷载结构法对该偏压明洞衬砌结构进行了有限元分析计算,分析了衬砌结构的位移与应力情况,得出能够保证隧道结构安全的设计方案,并总结论述公路偏压隧道病害防治措施。
Tunnel named Tou Dao Xue is a key project of Huaifeng highway.According to unsymmetrical load caused by around geological conditions in the open cut tunnel,considering unsymmetrically loaded retaining wall set up in the project,the finite element analysis on the lining structure is carried out by means of load structure method.The displacement and stress of lining structure are analyzed so that a design scheme ensuring safe tunnel structure is obtained.In addition,disease control measures of unsymmetrically loaded highway tunnel are concluded.
