摘　　要：以某生态文旅小镇项目为实例,梳理山地开发项目排水系统的特点,重点研究和总结大坡度道路排水管道系统的设计要点,主要包括排水管道系统的最大设计流速、管材选择、检查井、雨水口等,以此提高大坡度排水管道系统的经济性、合理性与后续运营的安全性。待项目竣工投入使用,后续可动态跟踪排水系统运营情况,为山地开发项目的排水管道系统设计提供可借鉴经验。Taking a certain ecological&cultural tourism town project as an example,it summarizes the characteristics of the drainage system in mountainous development projects,focuses on studying&summarizing the design points of the drainage pipeline system for large-slope roads,mainly including the maximum design flow rate of the drainage pipeline system,pipe selection,inspection wells,rainwater outlets,etc.,in order to improve the economy,rationality,and subsequent operation safety of the large-slope drainage pipeline system.After the project is completed and put into use,the operation of the drainage system can be dynamically tracked in the future,providing valuable design experience for the drainage pi p e l ine system design of mountai nous development projects.
