摘要

介绍了国内首个地铁联络通道强制解冻融沉注浆工艺的设计与施工。整个施工过程中对土体温度和地表变形进行了监测，得到了温度和地表变形的变化规律。由于冻结法施工中存在冻胀和融沉问题，过量的冻胀、融沉会对地表建筑和地下管线产生危害。结合工程实例，对强制解冻融沉注浆进行了研究，该工程对冻结加固体分区强制解冻、及时进行融沉注浆、二次加固土体，消除了后期压密沉降发生的可能，地表变形的监测表明强制解冻融沉注浆技术在该类工程中应用效果良好。

Abstract

The design and construction of thaw settlement grouting during forced thaw in the metro connected aisle project are described. Temperatures in soil as well as ground settlement are monitored during the construction. Frost-heave and thaw-settlement may exist in freezing project. Superfluous frost-heave and thaw-settlement can cause disaster. Based on the actual engineering

the paper studies thaw settlement grouting during forced thaw in the metro. The method of thaw settlement grouting during divisional forced thaw eliminates the possibility of consolidation settlement. Good effects has been achieved in this project from the ground settlement measured in situ.
