摘要
结合工程概况,介绍马家梁隧道洞口浅埋段目前的施工状况,对围岩变形原因进行分析,从超前支护的参数确定、施工工艺流程、施工要点等方面阐述了施工措施,并对超前支护的效果进行监测,以供类似工程参考。
Based on the actual construction,the paper introduces current situation of the construction of the shallow bias section of Majialiang Tunnel,analyzes the causes of the rock deformation,explains some measures from the parameter determination of advanced support,construction process and essentials and monitors the effect of advanced support.
