摘要
结合北京地铁4号线成府路车站联络通道工程特点,为了提高土体整体稳定性和承载力,保证地铁结构安全,分析了粉土地层的性状,采用水泥-水玻璃双液浆,并据土质情况确定浆液配比与注浆压力,对土体进行劈裂注浆加固,取得了良好效果。
Combined with the characteristics of connecting passage project of Chengfu Station in No.4 Line of Beijing Subway,through analyzing the properties of silt layer,cement-soluble glass binary slurry is used to reinforce soil mass with proper mixing proportion and grouting pressure according to soil conditions in order to improve soil mass stability and bearing capacity and ensure subway structural safety,which has achieved good effect.
