深埋隧洞突发性高压涌水预测及对策研究

Prediction and Countermeasures for Paroxysmal High-Pressure Blow of Deeply Buried Tunnels

文中介绍了几种典型高压涌水形成的地质条件,为了防止在隧洞掘进过程中出现突发性高压涌水,采用宏观地质预报、微观地质预报及探地雷达预报提前预测可能存在高压涌水的位置、水量和水压等,并且对一些富含高压水构造提出了一些相应的施工对策。

Geology conditions of typical high pressure blows were described in this paper, and it＇ s very significant for paroxysmal high - pressure blow forecasting in the process of tunnel drivaging. The position, water quantity and pres- sure of high - pressure blow can be predicted with technologies of geology macro - and micro - forecast and ground penetrating radar （GPR）. As a conclusion, construction countermeasures were also brought forward for structures of high - pressure water.
