【摘要】 隧道涌水是施工过程中经常遇到的一类地质灾害,给隧道施工带来安全隐患和经济损失,因此,对隧道掌子面前方的裂隙水发育情况进行准确及时的超前预报,具有重要意义。总结了常用隧道涌水量计算方法和裂隙水超前预报方法,并对各方法优缺点及适用范围作了比较。依托宜(昌)-巴(东)高速公路石门垭隧道工程,利用地质分析方法对隧道全段进行裂隙水发育情况和超前预报方案的划分,并结合涌水量计算与TSP预报系统对裂隙水进行预报,收到了良好的预报效果,对类似工程具有一定的指导意义。更多还原

【Abstract】 Water gushing was a kind of common geological hazards in tunnel construction process,which was a potential security risk and caused economic loss for the construction.So,it is crucial to give an accurate and immediate advanced prediction about the developing situation of fissure water in front of the tunnel face.This paper summarized current computational methods in tunnel water gushing capacity calculation and advanced prediction about the fissure water,and made comparisons about the merits and demerits and the applicability of these methods.Based on the Shimenya Tunnel Project of Yichang-Badong Highway,the fissure water developing situation of the whole tunnel and the advanced prediction program are divided by using geological analysis method.To forecast the fissure water in combination with the water gushing capacity caculation and TSP forecasting system,a good forecast result has been received,which can be taken as example for similar engineering.更多还原
