Support Optimization Analysis And Monitoring Technology Of The Tunnel Construction

In recent years, as our country rapid development in highway construction, highway tunnel as the focus of the development impact of highway construction, its liner structure on supporting is the focus of research in in which to achieve security、economic、 reasonable.This paper first describes the theoretical development status of monitoring and measuring, and then based on the specific situation of highway tunnel,the paper studies on monitoring and measuring in tunnel construction and.We have optimized the thickness of first and second liner of some highway tunnel, then reduce the cost;A systemic plan including items、method、disposal of data、rule of lining and management of constriction has been make;We have make a evaluate to the safety of construction and reliability of structure on base of the field test for surrounding rock of Ⅲ、Ⅳ、Ⅴ class;In order to evaluate the first and second liner of Ⅲ、Ⅳ、Ⅴ class with the software of FLAC.Thesis achievement arises to important technical support not only for the optimization design and safety construction,but also have valuable to the construction and management of highway tunnel in the future.
