摘要
介绍了城市几种地铁施工工艺的地面沉降控制情况，结合北京地铁施工中一个施工条件复杂的标段对于施工过程中地面沉降的控制要求，设计出一个超前大管棚开挖支护的试验施工方案，并对其施工过程做了详细阐述，最后对监测结果进行了分析。
It introduces land subsidence control condition of several subway construction techniques in city, designs a testing construction scheme of excavation and supporting by lead big pilot pipes combined with control requirement of a section with complicated construction condition on land subsidence in Beijing subway construction, illustrates the construction process, and analyzes its monitoring results.
