摘要
浅埋隧道进口段地质结构稳定性较差,常出现形变、开裂问题影响隧道工程质量。论文结合具体案例,对浅埋隧道施工地表开裂问题进行探讨,根据开裂情况、开裂原因采取弥补措施,加强隧道施工技术优化管理,弥补了不良地段施工地表开裂问题的影响,工程顺利通过,质量较好。
The stability of geological structure in the entrance section of shallow tunnel is poor,and deformation and cracking often occur,which affects the quality of tunnel engineering.In this paper,combined with specific cases,the surface cracking in shallow tunnel construction is discussed.According to the cracking situation and causes,remedial measures are taken,and the optimized management of tunnel construction technology is strengthened,which effectively compensates for the influence of surface cracking in bad sections.The project is successfully passed with good quality.
