Cause Distortion And Study Of Repair Measure In Xiling Xueshan Tunnel Of Da Shuang Road

Xiling xueshan tunnel lie in Taiping and Zhuojiang town of Dayi country in Sichuan province. Belong to the northeast line of main highway in park of nation forest in Chengdu Xiling xueshan and thermal spring of Huashui guy. It is the main artery that opens into Huashui Mountain and Xiling xueshan travel industry sites. At the same time it is the only tunnel in Chengdu town.This tunnel has happened many distortions from begin construct, and it continuanced use in the tunnel manage.This arose part collapse of tunnel or disease in differ degree.Bases observation and research to characteristic of engineering, instance of engineering geological , instance of hydrological geological and result of experimentation in locale, analyse cause of tunnel distortion in the region of swelling wall rock and effect mechanism of swelling wall rock. Calculate compressive stress of swelling wall rock by the finity units way integrate the data of experimentation in locale.Give collectivity distortion trend in zone of swelling wall rock tunnel. Adopt the finity units calculate way , explain tunnel distortion characteristic in swelling wall rock, analyse effect of compressive stress of swelling wall rock to distortion of tunnel.In the same time it is have done analyse that disease of tunnel because compressive stress, summarize the repair measure of tunnel disease and measure of construct technics in tunnel disease construct.Base on ananlyse result, put forward prevention and cure of tunnel disease and repair measure in the zone of swelling wall rock, provide reference idea for the same tunnel design , construction and so on.
