摘要
上海市某隧道旁通道是第一个参照《旁通道冻结法融沉注浆加固建设指导意见》完成自然解冻融沉注浆的旁通道。事实证明,其所有测点的沉降量均在控制范围内,《旁通道冻结法融沉注浆加固建设指导意见》是科学的。介绍了该旁通道的注浆加固施工工艺及加固效果。根据加固效果分析提出进行有效融沉注浆的建议:在开始融沉注浆的第一个月内应增加注浆频率和注浆量,可有效控制最终的沉降量;对距离旁通道轴线较近的隧道区域应进行强化注浆,可有效减小隧道的最终沉降量。
Shanghai subway contract channel is the first natural thaw settlement grouting channel based on the ＂Construction Guiding Opinion of Contract Channel Thaw Settlement Grouting Reforcement＂.This paper introduces the reinforcement construction technology and reinforcement based on the effect analysis,argues that the reinforcement could enhance the effect in the thaw settlement grouting.
