摘要
以深圳地铁某区间隧道穿越浅基础建筑物群为工程背景,根据详细的地质补充勘察数据计算盾构施工参数,通过准确的盾构施工参数模拟盾构推进过程,利用FLAC3D软件计算建筑物沉降,同时与现场实际施工过程和监测数据进行对比分析,采取二次补浆等施工措施确保建筑物安全。
Taking the section tunnel under building group with shallow foundation in Shenzhen Metro as engineering background,the shield construction parameters are calculated based on the detailed geological supplementary exploration data.The shield driving process is simulated by the accurate shield construction parameters.The building settlement is calculated by utilizing FLAC3D software.At the same time,the calculated results are compared with the field practical construction process and monitoring data.The construction measure of the second meeting pulp is adopted to ensure the safety of building.
