摘要
通过对广深地铁隧道所处地层条件的判断,分析了采用盾构法施工遇到孤石产生的影响和危害,提出了直接破碎孤石的条件和复合地层盾构机推进需注意的问题,最后阐述了几种处理球状风化孤石的方法,为复合地层盾构法施工积累了经验。
According to the judgment of the layer conditions of Guangzhou-Shenzhen tunnel, the paper analyzes the influence and diseases of the boulders in the shielding construction, points out the conditions for the direct broken boulders and the precautions in the shielding machine for the composite layers, and illustrates some methods to treat the spherical weathered boulders, so as to accumulate the experience for the shielding construction of composite layer.
