The High-speed Railway Landscape Corridor Sustainable Stormwater Management LID-BMPs Design

In the process of China’s high-speed rail going out of the country,The Dersert Express project environmental assessment requirements are very strict.The relevant laws and regulations explicitly require the Dersert Express project to adopt Sustainable Stormwater Management to mitigate the impact of railway projects on the water environment in the United States.Currently,the technology of railway drainage still stays in the traditional stage of stormwater management focusing on rapid discharge and flood control,and there is lack of systematic and comprehensive guidelines and standards for railway sustainable stormwater management.On the other hand,the impact of the railway on the water environment has always been there,but the sustainable stormwater management of Railways has not been fully developed due to economic,security,management and other conditions restrictions.Domestic railway design institutions are gradually paying attention to sustainable stormwater management under the background of sponge city construction in our country.This paper begins with the research on the sustainable stormwater management and the high speed rail landscape corridor:(1)the urgency and necessity of implementing sustainable stormwater management in high speed railway landscape corridor are analyzed;(2)Combing the sustainable stormwater management basic and core objectives,analyzes the relationship between the target and the core of high-speed rail construction.Screening and analysis of the impact factors of the implementation effect of high speed railway sustainable stormwater management goals,including two aspects of natural elements and unique elements of general landscape corridor in the high speed rail;(3)According to the analysis results of the factors affecting the implementation of sustainable stormwater management obstacles in the high-speed rail corridors,possibility and feasibility,put forward on the basis of high speed railway sustainable stormwater management target segmentation and construction method,and combined with the analysis of the suitability of the target simulation method for calculating the common sustainable stormwater management;(4)According to the analysis results of the influencing factors,this paper studies the applicability of the common measures of sustainable rainfall and flood in the high-speed railway landscape corridor,and puts forward a set of lid-bmps measures suitable for the construction of high-speed railway landscape corridor;(5)Combining the existing design process of high-speed rail construction and environment evaluation,Paper proposed a sustainable stormwater management design flow which is suitable for the construction of high-speed rail landscape corridor,which integrates target,calculation and simulation measures to form as a whole.(6)The design method,simulation method,lid-bmps measure setting and designing flow are carried through Desert Express Project in the US.It is a validation of the whole study...
