摘要:
重点介绍深圳市白石岭大断面公路隧道,在全-强风化的花岗岩及第四系坡、残积土施工中遇到花岗岩微风化球体的不良地质条件。由于大气降水、围岩渗水致使围岩缺乏自稳性,造成隧道连续大规模坍方冒顶,并列举典型事例,介绍事故处理措施、过程和效果,对施工中的经验教训进行了归纳总结,提出一些看法和建议。
Abstract:
Baishiling tunnel in Shenzhen is a highway tunnel with large crosssection. The tunnel goes through fullyheavily weathered granite and Quaternary alluvial and residual soils. Due to the slightlyweathered granite spheres encountered during construction and the lack of selfsupport ability of the surrounding rock mass caused by rainfall and water infiltration of the surrounding rock mass, largescale collapses and caveins occur consequently during the tunnel construction. In the paper, the typical collapse and cavein incidents are listed, the treatment countermeasures, treatment process and treatment effects are presented, the experience and lessons in the tunnel construction are summarized and some recommendations are made.
