Research On The Geological Environmental Impact Assessment Method Of The High-speed Railway Construction Based On System Dynamics

Due to its own characteristics such as high speed,fast,comfortable,the high-speed railways have won the support of people.Recent years,due to the national policy,high-speed railway has developed vigorously.Our country has entered into a“high-speed railway age”.However,the construction of high-speed railway is a double-edged sword,while driving along the regional economic development at the same time also brought great pressure on the environmental protection along the line,the construction of high-speed rail project on the ecological environment and the natural environment caused by cutting damage and damage Influence can not be ignored.This paper studies the system dynamics evaluation of the influence of high-speed railway construction on the regional geological environment,which has important theoretical research and practical application value to improve the accuracy and evaluation of the impact of high-speed railway construction on regional geological environment and improve the geological impact of high-speed rail construction.Based on the proposed high-speed rail assessment,this paper mainly studies the impact of high-speed rail construction on the regional geological environment,finds out the key influencing factors of the regional geological environment during the construction of high-speed rail,establishes the comprehensive evaluation index system of the impact of high-speed rail construction on regional geological environment,The method of system dynamics is used to calculate the causal relationship between each index,and the system dynamics model is established,and the simulation is carried out.In the actual case of high-speed rail to verify the construction model and index system of rationality,scientific and practical.This paper analyzes the current situation of the research at home and abroad,the purpose of the study and the relevant theories of the high-speed rail assessment.The impact of the high-speed rail construction on the regional geological environment is analyzed,and the comprehensive evaluation index system of the high-speed railconstruction on the regional geological environment is established according to the relevant evaluation criteria.The principle of system dynamics is expounded,and the application of system dynamics in the evaluation of regional geological environment is discussed.For the future construction of high-speed rail project,the election line,design optimization to provide decision-making basis.
