| 摘 要： | 结合中国第一条双圆隧道工程施工,对双圆隧道盾构推进对周围环境影响的现场监测方法进行了论述.文章以双圆盾构隧道区间施工为实例给出了双圆盾构推进过程中周围土体的变形、土压力、水压力变化的监测方法与测点布置方案,据此监测方案,可以详细监测与分析盾构推进过程中周围土体的地表变形、深层土体变形及土体中的土压力、水压力的变化,从而揭示盾构推进对周围的土体环境的扰动影响规律.

| Abstract: | This article presents an on-site testing of the construction site surroundings during construction of a Double-O-Tube(DOT)tunnel.During the process of the first DOT tunnel construction in China,Shanghai Tun- nel Engineering Co.,Ltd.undertook detailed monitoring analyses on the construction site surroundings in the proce- durcs of tunnel construction such as surface settlement,deep soil deformation,inclination of strata,water pressure and soil pressure etc.Accordingly much were obtained of first-hand monitoring data,which are very useful to under- stand in depth the characteristics of the soil in DOT tunnel construction.At the same time,this work builds up ample information resources for further exploration of DOT tunnel construction. |
