摘要

以象山隧道3#斜井工区正洞帷幕注浆施工为例，对比3个不同地质段的帷幕注浆施工情况，对全断面帷幕注浆、周边帷幕注浆、局部帷幕注浆3种不同的注浆方案进行探讨，分析不同水文地质条件下注浆方式的选择对施工进度的影响，寻找最优的注浆方案，优化注浆施工和施工组织技术，达到控制成本，缩短工期的目的。

Abstract

The curtain grouting constructions in 3 different hydrogeological sections of the main tunnel in No. 3 inclined shaft work lot of Xiangshan tunnel are compared. Three different grouting schemes, i.e., fullface curtain grouting, surrounding curtain grouting and local curtain grouting, are discussed. The influence of different grouting schemes on the construction efficiency under different hydrogeological conditions is analyzed. Optimal grouting schemes are determined, the grouting technology and the construction organization technology are optimized, which achieves better controlled construction cost and reduced construction period.

Key words： curtain grouting; scheme optimization; rapid construction; wall for grouting; construction organization
