摘要
玻利隧洞为强岩溶管道发育地区深埋、高地下水位长隧洞,汛期工程区普降暴雨,造成已衬砌隧洞底板局部混凝土发生了隆起、开裂破坏。为此,采用洞内修复加固和洞外增设排水洞等工程措施进行了处理,经2016年汛期验证,修复加固效果良好,其经验可供类似工程设计参考。
Boli tunnel is a deeply buried long tunnel accommodated in a karst pipe intensely developed zone with high underground water level. This tunnel has concrete lining, but heavy rains during flood season caused local up- lift and cracking of concrete floor slab. Repair and reinforcement were conducted inside tunnel while additional drainage holes were constructed outside. The tunnel has withstood the flood season of 2016, showing good effects of repair and reinforcement measures.
