摘要
针对成渝高速公路复线缙云山隧道左洞K4＋183~K4＋170段发生的突泥涌水现象,采用超前地质预报手段查明了溶洞纵向及底部范围,根据岩溶发育规模提出了清淤、封端、回填、注浆的处理方案,解决了隧道岩溶突泥治理问题。
The paper analyzes mud bursting phenomenon at K4 ＋ 183 - K4 ＋ 170 section of left Jinyunshan tunnel hole of Cheng-Yu highway, investigates vertical and bottom karstic scope by applying advanced geology prediction method, and puts forward desihing, blocking, backfilling and pouring treatment scheme according to the karst development scale, and finally solves tunnel karstic mud bursting treatment problem.
