【摘要】 隧道穿越软弱围岩及断层破碎带路段时,容易产生突发性地质灾害,直接威胁施工人员和设备的安全。本文结合山西省第一长隧道——宝塔山特长隧道的工程实践,介绍了隧道穿越软弱围岩及断层破碎带路段的衬砌结构设计及施工防治措施,同时着重分析了超前帷幕注浆设计及施工的关键技术,可供同类工程设计和施工参考。更多还原

【Abstract】 When tunnel traverses weak surrounding rock and fault cracked strip,it is easy to bring paroxysmal geological disaster in course of digging and it directly threatens the security of builders and equipments.For the engineering example of the first longest tunnel,the Baotashan tunnel in Shanxi province,the lining structure design and construction prevention and cure measure when it traverses weak surrounding rock and fault cracked strip are introduced.Key technologies about the design and construction of advance curtain grouting are addressed, which can provide reference for analogous engineering’s design and construction.更多还原
