摘　　要：在隧道施工中,现场监控量测往往仅判断围岩、结构是否稳定,而对支护时机是否及时则很难判断。以铜锣山隧道为例,采用数值模拟方法,对Ⅴ级围岩绘制围岩、支护特征曲线,并结合监控量测数据分析,判断支护措施及支护时机是否合理,同时给出围岩压力测试数据,指导隧道施工。During tunnel construction,site monitoring only judges surrounding rock and structure for safety,but it is difficult to judge whether supporting is in time.In this paper,with Tongluoshan Tunnel as an example,using numerical simulation,characteristic curve of surrounding rock and supporting is drafted for V-class wall rock.Combined with monitoring data analysis,supporting measure and supporting time are judged for rationality.Meanwhile,surrounding rock pressure testing data is given to guide tunnel construction.
