基于实测数据统计的深埋特长隧道施工监控量测技术研究

Research on Monitoring and Measurement Technology of Deep Buried Super Long Tunnel Construction Based on Statistics of Measured Data

围岩和初支接触压力规律是隧道施工和支护设计的中心工作,一直是隧道工程界研究的热点问题之一。在通过对某隧道和两路口隧道监测断面围岩压力的统计分析,以及对该隧道地质及支护观察、周边位移、拱顶下沉监测的基础上,并进行了围岩和初支接触压力的规律监测,研究深埋特长隧道施工监控量测技术研究分布特征。

The law of contact pressure between surrounding rock and primary support is the central work of tunnel construction and support design,and has been one of the hot issues in tunnel engineering.In this paper,the surrounding rock pressure of a tunnel and two intersection tuirnel is analyzed statistically.The tunnel geology and support observation,peripheral displacement and vault subsidence are monitored.The law of contact pressure between surrounding rock and primary support is also monitored.At last,this paper studies the distribution characteristics of monitoring and measuring technology for deep and long tunnel construction.
