水工隧洞衬砌裂缝检测与安全分级评价
Lining crack detection and safety classification evaluation of hydraulic tunnel
摘要
Abstract
Lining cracks are the main diseases of tunnels,however there are no evaluation system of tunnel lining safety.In order to solve this problem,this paper proposes a new evaluation system,which takes the cracks,construction joints,crushing and spalling,and deformation as parameters.Based on the four evaluation indicators,a comprehensive quality evaluation system of tunnel lining concrete cracks is proposed.It can quantitatively and accurately evaluate the lining cracks from part to whole and give out the evaluation result of lining cracks.Based on the project example,it is proved that this evaluation system is feasible and provides an important foundation for the repair and reinforcement of the tunnels.And it also offers a reference for the evaluation of similar lining cracks.关键词
