【摘要】：隧洞涌突水是隧洞施工過程中的一個重要巖溶水文地質(zhì)問題,特別是隧洞在可溶巖徑流區(qū)附近穿越時,其涌突水問題可能將是制約性工程問題。隧洞遭遇嚴(yán)重涌突水,直接影響工程施工,對工程本身形成一定程度制約因素,此類問題影響工期、造價等,嚴(yán)重時影響工程的成立與否。通過研究適宜的防治對策,對隧洞施工過程中涌突水災(zāi)害,堅(jiān)持"預(yù)防為主,防治結(jié)合"、"有疑必探,先探后掘"的方針,采取"探、放、堵、截、排"綜合措施。立足于采取主動措施,防范于未然,同時提前擬定處理預(yù)案,以應(yīng)不時之需。
[Abstract]:Tunnel water inrush is an important karst hydrogeological problem in the course of tunnel construction, especially when the tunnel passes through near the run-off area of soluble rock. The problem of water inrush may be a constraint engineering problem. The tunnel encountered serious water inrush, which directly affects the construction of the project, which has a certain degree of constraints on the project itself, such problems affect the duration of the project, cost and so on. In serious cases, the establishment of the project is affected or not. Through the study of appropriate prevention and control countermeasures, the principle of "prevention as the main, prevention combined" and "probing first and then digging" is adhered to in the course of tunnel construction. Take comprehensive measures of "probing, releasing, blocking, intercepting, and discharging". Based on taking active measures, take precautions against them, at the same time, draw up and deal with the plan in advance so as to meet the need of time.

【正文快照】： 1 研究背景 巖溶涌突水是指隧洞開挖過程中,由于巖溶發(fā)育而形成的地下水集中或分散的出流現(xiàn)象。巖溶涌突水是隧洞工程建設(shè)中經(jīng)常遇到的現(xiàn)象,與一般巖體裂隙性涌突水比較,具有以下特點(diǎn):(1)巖溶涌突水發(fā)生的部位具有很大的不均一性,主要是由于巖溶發(fā)育的不均一性所致;(2)巖溶涌
