1、交通运输论文- 广州地铁2号线区间隧道盾构施工引起的地面沉降规律分析【提 要】:本文对广州地铁2号线赤—鹭区间盾构隧道施工过程的地面沉降监测数据进行分析,探讨了盾构施工过程地表沉降规律及其影响范围和程度,包括沉降槽分布形式、沉降随时间发展规律、沉降量概率分布的统计分析等,并用数学函数加以表达。研究结果对今后类似工程施工过程的隧道周边建(构)筑物的保护,施工参数的优化以及工程的顺利实施具有参考价值。【关键词】:地铁盾构沉降统计Abstract: Analysis of monitored ground settlement data upon shield d
2、riving at Chi Lu running section, Guangzhou Metro No.2 line, to make an approach to ground settlement mechanism during shield driving and its affected scope and extent, including settlement trough distribution pattern, settlement vs time graphic, settlement probability distribution
3、, and other statistical analyses, expressed in mathematical functions, the resulting findings could be referenced for peripheral buildings/structures protection of similar construction sites, optimization of construction parameters and smooth execution of similar projects.Keywords
