| 摘 要： | 近年来为满足规划、平面线型要求,受地形、地质、地面构筑物的影响,双线地铁隧道呈迅猛增加的趋势。且大多数地铁区间隧道中,通常在同一埋深地层平行修筑两条隧道。广州轨道交通5号线淘金―区庄区间隧道具有穿越地层复杂、隧道断面、间距、埋深均随里程而变化的特点。两条隧道的开挖将导致地表沉降相互影响,沉降预测更加困难。在概化地质模型的基础上,利用反演得到地层参数,选择典型隧道断面及地质剖面,采用数值方法分析不同间距、隧道埋深以及地层情况对地表沉降的影响。得出一定的规律,预测隧道施工引起的地表沉降,以指导实际工程的安全施工。

| Abstract: | In recent years,the parallel dual-subway tunnels have increased rapidly because of the need of planning and plane design,the restriction of terrain,geology and surface construction.The parallel dual-subway tunnels are often constructed in the same buried depth of most metro running tunneling.Taojin-Quzhuang running tunneling in rail transit # 5 of Guangzhou City has running within complex strata,and tunneling section,space between dual-subways,buried depth vary with mileage.Surface settlement will be intera... |
