摘要
结合高速公路工程隧道施工中的监控量测实例,就隧道围岩现场监控量测方法和对量测数据的处理和分析进行了阐述,通过对测量结果指导,可及时对出现的故障险情采取措施,保证施工人员生命安全。结合隧道出口洞内顶拱下沉记录为基础数据,分析2013/4/27到2013/5/5隧道出口总下沉量与时间关系,并用监测结果修改初步设计,指导施工,确保施工安全。
Combined with the example of highway tunnel construction,this paper expounds on-site monitoring and measurement methods of tunnel surrounding rock and the processing and analysis of measurement data.Through the guidance of measurement results,measures can be taken in time for the failure and danger to ensure the life safety of construction personnel.Based on the settlement records of top arch in tunnel exit,the relationship between total settlement of the tunnel exit and the time from April 27,2013 to May 5,2013 is analyzed.And preliminary design is modified through the monitoring results,which guide the construction and ensure construction safety.
