摘要
初步总结了国内外山洪沟治理工程技术进展和发展趋势,对山洪沟治理工程设防标准、工程设计原则、各种工程措施布置原则、山洪沟治理与中小河流治理及水土保持工程区别与联系、山洪沟治理的各种工程措施的技术要求等作了初步探讨。总体而言,山洪沟治理工程措施主要布设在县城、村镇、人口密集居民点、重要基础设施等处,以治点为主,以护岸消能防冲为重点,根据山洪沟所在的地形、地质条件,植被及沟壑发育情况,因地制宜,综合治理,形成以护岸及堤防工程、截洪沟及排洪渠工程、沟道清淤疏浚工程、分洪道及排洪渠工程为主,必要的谷坊、格栅坝、陡坡、跌水、滞洪带等措施为辅的综合防治体系。
A summary is given on the technology advancement and trend of control measures for valleys flushed by mountain flood in China, and relevant standard, criteria and display principles. Discussions are made on the differences and relationship between small and medium river harness and soil technical requirements of varied structural measures. Generally s conservation with mountain flood prevention, as well as peaking, structural measures are mostly placed in densely populated areas in the center of county, village, residential areas and key infrastructures. A comprehensive prevention system is built by focusing on consolidating vulnerable sites and banks, in line with landscape and local geological and vegetative conditions, together with a series of waterworks such as revetment, embankment, flood retention ditch and drainage canal, dredging of valley channel and spillway that supplemented by check dam, geogrid, steep slope, water drops and flood retention belt.
