| 摘 要： | 结合西藏嘎隆拉隧道施工中出现的严重突水、涌水灾害,应用ABAQUS中的动态仿真技术,依据流固耦合理论,对注浆堵水层厚度进行优化研究。计算结果表明,当厚度超过3m时,隧道断面排水量低于150m3/d,并基本趋于一致。计算结果应用于嘎隆拉隧道工程施工中,取得了良好的堵水效果。

| Abstract: | An optimization research was conducted on the thickness of grouting layer for blocking water based on the technique of dynamic simulation in ABAQUS and the fluid-solid coupling theory with the case study of the serious disaster of water inrush in the construction of Galongla tunnel in Tibet. The results show that when the thickness is more than 3 m, the water discharge of tunnel section is less than 150 m3/d and tends to be consistent. The calculation results have been applied to the Galongla tunnel engineering construction and achieved a positive effect for water plugging. |
