摘要
在岩石饱和抗压强度低于5MPa的岩体中修建长隧洞,如何保证围岩稳定,进行安全施工是最突出的问题。国内外在软岩隧洞施工过程中经常遇到塌方事故发生,造成人员伤亡、设备损失、工期延误,投资增加。在极软岩层中建成的15km长的顶山隧洞,采用了信息化的设计和施工方法,保证了施工安全,工期提前半年,节省了工程建设资金并取得了工程建设质量优良的效果。
In the construction of long tunnel in the rock with the saturated compression strength below 5 MPa,one of the pivotal questions is to ensure the stability of the surrounding rock and safe construction.In the construction of tunnel in soft rock in both domestic and overseas engineeringt,he frequent collapses of rock often cause the loss of lives and equipments,the delay of time limit of the project and the increase of engineering investment.While in the successful construction of the 15 km long Dingshan tunnel in soft rock,with the use of informative design and construction technique,the safety of construction is ensured,six months of the time limit and the investment of construction are saved,and the eminent construction quality is achieved.
