上海软土地层中运营地铁隧道不均匀沉降的治理方法

摘要/Abstract

摘要： 针对上海饱和含水软土地层及地铁隧道维修保养的实际工况，提出了革新劈裂注浆的土层微扰动注浆治理方法.利用夜间地铁停运的积累时间，采用适合上海运营地铁隧道实际条件的简易设备和施工操作方法，在地铁隧道内部治理运营隧道的不均匀沉降，选取适合的注浆工艺、材料、设备和参数并通过工程实例，分析注浆设计、施工的过程及其效果.结果表明，所用方法能够减少注浆对地层的扰动，对地层沉降具有良好的补偿效果，可以较好地治理运营地铁隧道的不均匀沉降.

Abstract: In the light of the actual condition of Shanghai very soft water saturated ground and the remedial maintenance of metro tunnel, slight soil disturbance grouting disposal method, which is the renewal of fracture grouting, was performed to treat unequal settlement of Shanghai metro tunnel with relatively simple equipment and easy handling which are suited to local condition of Shanghai. The method was carried out in operated tunnel by use of the accumulative times of nightly stopping of subway operation. The choice of grout technology, grout equipment and grout construction parameters were described. Through the engineering example, this paper detailed the design and construction of this grouting program as well as the result of practice. The results indicate that this method can treat unequal settlement of Shanghai metro tunnel by minimizing soil disturbance induced by grout injection and achieve good compensation effect of ground settlement.

Key words: soft ground, metro tunnel, unequal settlement, grouting disposal
