    摘要
  • 摘要: 上海轨道交通十号线溧阳路地铁站与运营的四号线海伦路地铁站斜交，该场地多为饱和砂质粉土地层，下伏双层承压水，且承压水在换乘站南侧交汇，这对基坑开挖与复杂的周边环境、尤其运营四号线的保护提出诸多技术难题。针对该工程的特点，对比分析了基坑中地下水处理措施的优缺点，提出了水平封堵的地下水处理技术，并采用理论分析和三维有限元模拟研究了水平封堵位置以及封堵厚度等参数变化对基坑变形和周边环境的影响，然后针对可行的水平封堵方案进行了优化处理。基坑施工中的现场监测结果证明了其可行性，该成果对类似工程具有参考意义。
    Abstract: The subway of Line 10 at Liyang Road has an interchange station with the opening subway of Line 4 at Hailun Road. The site is underlain by several different sandy-silt layers and double-confined water layers, and the double-confined water gets together at the south side of the interchange station, which causes a lot of technical problems, such as pit excavation, environmental impact and protection of the safe operation of Line 4. For this project, the characteristics of different ground-water treatment methods are analyzed, and the horizontal sealing technology is proposed. The location and thickness of the horizontal sealing layer are analyzed and their effects on pit deformation and its surroundings are studied through theoretical analysis and three-dimensional finite element simulation, and the optimization of the horizontal sealing measure is carried out. The feasibility is proved by means of the monitoring results during excavation, and the results are useful to similar projects.
