摘要
麻栗坝水库工程地质条件复杂,存在需要在超深软基上布置输水建筑物等难点技术问题有待解决。在反复分析论证的基础上通过采用注浆管棚等施工技术,成功地在高地下水位低胶结度的砂性土中开挖隧洞,实际过水应用表明设计施工是合理可靠的。
The geological condition for Marliba Reservoir Project is quite complicated, for which some technical problems are to be solved there, such as the water conveyance structures have to be arranged on super-deep soft foundation. On the basis of repeated analyses and verifications, the construction techniques of shed-pipe grouting etc. are adopted therein, with which the tunneling in low-cemented sandy soil is successfully carried out under the condition of higher ground water level, and then both the design and construction are demonstrated to be reasonable and reliable through the actual water delivery operation.
