摘要
管网是海绵城市的主要设施,其布署是否合理直接影响海绵城市的效益。本文基于内涝数据和管网布署节点数据,首先建立内涝预测区域模型和管网设施布署抽象模型,通过管网设施节点覆盖率对管网布署进行评估;然后采用Spark并行化计算方法提高计算效率;最后利用该方法对沣西新城管网布署进行评估,针对不同重现期下的多次降雨,其覆盖率平均在90%以上,说明管网布署比较合理。该评估方法为海绵城市管网设施的布署和维护提供了重要的理论依据。
Pipe network is the main facility of sponge city,and whether the distribution is reasonable directly affects the benefit of sponge city.In the paper,based on the data of water logging and pipe network deployment nodes,the regional models for water logging prediction and pipe network facilities deployment are built.Then,the deployment of pipe net facilities can be evaluated based on node coverage calculated by Spark parallelization to improve the computational efficiency.Finally,the pipe network deployment in Fengxi New Town is evaluated,and the average coverage rate is more than 90% for multiple rainfall in different recurrence periods,indicating that the pipe network deployment is reasonable.This evaluation method provides an important theoretical basis for the deployment and maintenance of sponge city pipe network facilities.
