摘要
以某轨道交通盾构区间为例,总结了泥水盾构在软弱地层中下穿浅基础建筑群施工关键技术,从掘进参数控制、地表WSS注浆、洞内注浆及补充注浆等几个方面介绍了地层变形控制措施。从监测数据分析结果看,上述关键技术避免了建筑群出现沉降或开裂的情况。
Taking a rail transit shield section as an example,construction technologies of slurry shield passing through shallow foundation buildings in weak stratum has been summarized.Deformation control measures are discussed from excavation parameters,WSS grouting,grouting in the tunnel,supplementary grouting and so on.From monitoring data,the settlement or cracking of buildings is avoided.
