本文在对乌鲁木齐轨道交通2号线地质条件分析的基础上,结合以往研究工作和野外实地调查,对研究区抗浮水位的设计进行详细分析,并通过数值模拟法计算预测百年一遇洪水工况下轨道交通2号线地下水水位的上升幅度和趋势,最终确定乌鲁木齐市城市轨道交通2号线一期工程抗浮设防水位的合理建议值。进而可以解决百年一遇洪水情况下的乌市轨道交通2号线抗浮设防与防渗水位问题,并提出相应的成果,满足工程设计的要求。
Based on the analysis of the geological conditions of Metro Line 2 in Urumqi, combined with the previous research work and the field investigation, the design of anti-floating water level in the study area is analyzed in detail. The numerical simulation method is used to predict the flood conditions Under the rail transit line 2 groundwater level rise and trend of the ground, and ultimately determine the Urumqi city rail transit line 2 of the first phase of anti-floating waterproofing reasonable advice. Which can solve the problem of anti-floating fortification and seepage water level of Urumqi Metro Line 2 in the case of a hundred-year flood and put forward corresponding results to meet the requirements of engineering design.
