摘要
结合深圳地铁一期工程第六标段科华区间暗挖隧道工程实例,分析了软弱富水地层的沉降特性和引起地层沉降的原因,根据沉降原因提出了严格执行“十八字方针”、适度排放地下水、讲究开挖施工方法等控制对策,为软土地层进行城市地铁暗挖隧道有效控制沉降提供借鉴。
In combination with the instance of concealed tunnel excavation work in the Kehua section under the sixth tender segment of the Shenzhen Subway Project Stage Ⅰ, settlement of the weak soil strata with plenty of water is analyzed and control measures are suggested as per the settlement causes, Reference is offered for effective control of settlement in concealed tunnel excavation works of urban subways in soft strata.
