基于低影响开发的海绵城市道路项目绩效评价及设计研究

重庆大学硕士学位论文英文摘要ABSTRACTWith the acceleration of global warming and urbanization,traditional extensivedevelopment models have led to increasingly prominent social and ecologicalenvironmental problems such as low-lying urban water accumulation,frequentwaterlogging,water pollution,and water shortages.Traditional urban waterloggingsolutions rely too much on rainwater pipeline systems,with single measures and lowwaterlogging prevention capabilities,which cannot meet the drainage needs of urbanwaterlogged areas.It is imperative to explore new solutions to prevent waterlogging andwaterlogging.Urban roads occupies an important position in the sponge city.They arean important place for the generation and discharge of rainwater runoff and an importantpart of the construction of the sponge city.Therefore,the systematic design and researchof urban roads under the concept of sponge city is of great significance.The thesis first clarified related concepts,analyzed the relationship between thesponge city road system and low-density development,and summarized the applicationobjects of low-density development facilities in urban roads.On this basis,the spongecity road project related investment evaluation index system was constructed,and thetechnical plan of the sponge city road construction on Nansha Avenue,Guangzhou,Shenzhen was studied,and the following main results were achieved:The paper first learned about the main indicators of sponge city road projectevaluation based on low-impact development through literature analysis,and learnedfrom the Ministry of Housing and Urban-Rural Development "Sponge CityConstruction Performance Evaluation and Assessment Indicators (Trial)"system,through expert interviews,from environmental benefits The evaluation index system ofsponge city road projects based on low-impact development is constructed from threeaspects,economic benefits and social benefits,and specific methods for quantifyingsome indexes are discussed.Secondly,starting from the actual situation of urban roads in China and drawing onrelevant domestic and foreign engineering experience,the planning and design systemof the sponge city road system is constructed,which is specifically divided into:1Analyze the sponge city road design and summarize the sponge city roads and traditionsThe difference between urban roads;2 The selection of low-impact developmentfacilities for urban roads and their combined optimization design;3The selection oflow-impact development technologies and facilities for the land outside the red line of
