| 摘 要： | 无论是国内还是国外,在地铁修建过程中,都会不可避免的遇到地铁下穿河流或者其他地下水丰富的区域。土层内丰富的含水量必定会给地铁区间隧道的施工带来较大影响,甚至会造成渗水、流砂等施工事故。以南京地铁二号线工程莫愁湖-汉中门区间为例,分析比较3种不同施工方案下隧道地质的稳定性及渗流特性,研究结论可为地铁设计及施工给予一定的指导。

| Abstract: | Inevitably, the tunnels of the metro would cross the river or the area where it is rich in water when the metro is built both in and out board. And it is sure that the water would make a great effect to the constructing of the tunnels. Even the accident such as quicksand, piping could be caused. Verified with the tunnels from Mochouhu to Hanzhongmen, which is a part of the second line of Nanjing Metro, three methods are compared to find out the stability and the osmotic characteristics of the tunnels crossing the rivero The result of the paper can provide a theoretical basis for the metro designing and construction. |
