摘要
本文总结探讨了北京地区砂粘土层中浅埋隧道应用加泥式上压平衡盾构施工时的几项关键技术,包括盾构选型,开挖面稳定控制技术,背后充填注浆技术,地面沉降控制技术和纠偏技术,文章详述了盾构施工引发的地面沉降发展变化规律、可塑型背后充填浆液及目标土压力的设定。
Several key technigues including the type of shield,control technology of working place, technology of pulp-injecting at back and control and correction technology for surface subsidence used in balance shield construction for the sandy clay in Beijing are studied and summarized in the paper. And the changing regulation of surface subsidence and the setting of objective soil pressure for pulp-injecting at back are discussed also.
