基于GIS的高速铁路绿色选线声屏障动力学及景观设计研究

Railway noise prediction and control measures are one of the key problems in high-speed rail construction. Building sound barriers is one of the most effective and practical means of technology to reduce the noise pollution, and how to find the most secure barrier dynamics and landscape design is a key in its design.This project is to investigate the key technical issues on high-speed rail barrier dynamics and its landscape design, and to develop the theories and the methods in a high-speed rail green line barrier option dynamics and landscape design. Many damages to the environment can be avoided in planning and design stage using a combination between a green GIS platform and the railway line barrier option dynamics and landscape design.The research contents include: the dynamic response of the stress characteristics of the high-speed train operation and the sound barrier; the measurement and extraction of the design parameters of the high-speed rail barrier; the impact factor analysis on the high-speed railway sound source acting against the noise barrier; investigation on the anti-pulse power simulation for high-speed rail barrier;The calculation on the static the dynamic loads as well as the structure design on high-speed railway sound barrier; the dynamic characteristics of the high-speed rail barrier, and the simulation on noise reduction effect as well as the tests; research on the green barrier option and the landscape design for a high-speed rail based on GIS; development of the software for the research methods and the validation.
