双连拱隧道现场施工围岩压力、钢支撑内力等监测及分析

Monitor and Analysis on Wall Rock Pressure and Steel Brace Inner Force of Continuous Double-arch Tunnel Field Construction

该文根据浙江省诸永高速公路璜山2号隧道的施工监测,对监测数据进行分析,得出了双连拱隧道围岩压力、钢支撑内力和锚杆轴力的变化规律,研究成果对于连拱隧道的设计、施工及监测具有一定的指导和借鉴意义。

Based on the construction monitor of Zhejiang Province Zhuyong Expressway Huangshan No.2 Tunnel,the article analyzes the monitoring data,and gives the varying rules of wall rock pressure,steel brace inner force and bolt axial force of the continuous double-arch tunnel.The studying result has some instruction and reference for the design,construction and monitor of continuous arch tunnel.
