- 摘要:
- 针对南方某机场卫星厅工程以及配套站坪工程设计项目，为了分析卫星厅及站坪区域内排水能力与内涝风险，提高机场安全运行保障能力，开展机场卫星厅及站坪区域雨水管网评估研究。传统管网排水能力评估往往采用推理公式法，该方法适用于特定重现期和满足一定条件的管网，而机场卫星厅屋面通常采用的是大型虹吸排水，进入管渠瞬时流量较大，因此推理公式法不适用于机场雨水管网排水能力评估。为此，基于水力模型法，建立多维水力学模型，精确评估机场卫星厅及站坪区域内的排水能力与内涝风险。评估结果显示，在自由出流工况下，航站楼区域管网基本可以达到设计排水能力，但仍有部分跑道区域地面积水风险较高；在排口2 m水位淹没出流工况下，规划区管网超载风险较高，现状外围明渠涝点较多，核心区排水顺畅；在降雨峰值时排水渠有充足的空间承接屋面虹吸雨水，屋面虹吸管接入处虹吸雨水会对排水系统产生一定的偏向，但不会影响到主流。
- Abstract:
- Aiming at the design project of satellite hall project and supporting station platform project of an airport in South China, to analyze the drainage capacity and waterlogging risk in the satellite hall and station platform area and improve the safe operation support capacity of the airport, an evaluation project of rainwater pipe network in the satellite hall and station platform area of the airport was carried out. Traditional drainage capacity evaluation of a pipe network usually adopts the reasoning formula method, which is suitable for the pipe network with a specific return period and certain conditions. However, roof of the airport satellite hall usually adopts large siphon drainage, and the instantaneous flow into the pipe channel is large. Therefore, the reasoning formula method is not suitable for drainage capacity evaluation of airport rainwater pipe network. A multi-dimensional hydraulic model was thus established to accurately evaluate the drainage capacity and waterlogging risk in the satellite hall and station platform area based on hydraulic model method. According to the evaluation results, terminal area pipe network reached the designed drainage capacity in the case of free outflow. However, there were still a few runway areas with high waterlogging risk. In the case of submerged outflow with 2 m water level above the outlet, the overloading risk of the pipe network in the planning area was large, there were many waterlogging points in the peripheral open channels, and the drainage in the core area was smooth. At the peak of a rainfall, the drainage channel had enough space to undertake the roof siphon rainwater. The siphon rainwater at the entrance of the roof siphon pipe led to a certain deviation of the drainage system, but it had no influence on the mainstream.
