土压平衡盾构掘进地表沉降规律及控制方法

On the laws of ground surface subsidence and controlling methods with earth pressure balance shield entry-driving method

对采用盾构法施工引起地表沉降的一般规律及类型进行了介绍,阐述了地面沉降产生的原因和机理,并对地面沉降量的大小,分布及具体控制方法作了说明,以期指导实践。

This thesis introduces the common laws and types for ground surface subsidence caused by shield entry-driving construction method, expounds the causes and mechanism of ground surface subsidence, and illustrates the size, distribution, and specific controlling methods of ground surface subsidence, with a view to guide practice.
