Environment Risk Assessment Research Of Road Which Construction On Low Mountains

Environmental risks highway project planning, construction and operation of anacute problem can not be avoided. Environmental risks highway projects mainly inthe planning phase of route selection scheme is irrational, does not regulate theconstruction phase of the project design and construction organization and itsoperational period defect problems caused many accidents or derivative regional riskhazards. A short history of the development of risk assessment, the application of itsdomestic system is mainly related to the project petrochemical, nuclear, hydropowerand other high risk industries category. With the gradual increase in environmentalphilosophy, cognitive science and the people of the Franco-Prussian level, as thenational economy arterial highway project construction and operation will onlyalienate its evaluation of environmental risks into their overall planning anddecision-making to promote improved environmental quality, to reduce thefrequency of accidents, derivative harm reduction and social order and stability.Technology Environmental Risk Assessment section of this paper, the typical lowmountain topography area road projects in Sichuan Province Line Road, NorthRegion S202EIA projects, risk assessment for the first exploratory low mountainroad system construction projects carried out and risk management systemconstruction. Its main contents and arguments are as follows:(â… ) Comparative risk assessment process and the development of home andabroad, summarized the shortcomings and lack of domestic risk assessment system,the domestic system construction and application of environmental risk is mainlyconcentrated in high-risk, high-risk areas, there is no system architecture for lowmountain highway projects. This is the first proposed building for environmentalrisks typical low mountain highway project evaluation system and its correspondingmanagement system, to fill the field of environmental risk assessment applies to thecharacteristics of the low mountainous terrain highway project risk assessmentblank.(â…¡) In this paper, construction methods and operational features of its road projects under analysis geomorphological features low mountain areas, combinedwith its composition and affect the characteristics of the system to determine theappropriate risk assessment procedures, risk evaluation and risk category. And riskassessment and quantitative qualitative conclusions drawn conclusions acceptablelevel of risk analysis to identify risk factors for coordinated analysis and managementsystem organization and implementation of dynamic equilibrium.(â…¢) Establish low environmental risk assessment system mountain highwayprojects include: evaluation of grade determination, the scope of the evaluationreceptors, evaluation methods and risk factors to identify the type and scope.Evaluation grade evaluation indicators are: population density along the line,functional, regional sensitivities and regional history of the social environment riskassessment area. Evaluation receptor scope includes: population health, waterenvironment, air environment, sound environment and social stability. Evaluationmethods are: Data analyzed with state of the environment monitoring, source termrisk analysis, risk identification and risk assessment value.(â…£) Through the low mountain highway project environmental riskidentification and analysis of the ecological risk, the risk of natural disasters,accidents and social stability of the type of risk analysis and risk-line combination ofqualitative and quantitative evaluation, focusing on the risk of harmful consequencesthan the Explosion risk of accidents and serious toxic contamination risk withreference to the establishment of a mathematical model to estimate the prediction andsimulation, with an emphasis on regional risk of dangerous accidents exponentialrate of deflagration accident prediction and extreme energy estimates.(â…¤) Proposed for the corresponding low environmental risk assessment systemmountain highway project management methods, prevention measures andemergency plans. Management methods are: risk classification, risk identificationanalysis, risk management and risk monitoring plan developed. And by optimizingthe construction organization, innovative construction techniques and equipment,construction, construction management, professional teams and other ways tostrengthen the establishment of prevention and control of highway constructionproject environmental risk measures system. Through emergency warning, disasterhistory analysis, monitoring and maintenance and establishment of emergencycenters and other ways to build environmental risk prevention measures operatingsystem of highway projects.(â…¥) In this paper constructs evaluation system and management system for the evaluation of instances provincial highway S202line segment Ping changenvironmental risk assessment studies. Road wear by regional evaluation studyincludes: Regional Residential air and sound environmental impact of constructionprojects covering the area, along the resettlement project, regional soil erosion andecological trends in self-healing forces, regional risk assessment and dangerousaccidents regional natural disaster risk assessment. Analysis of the research processand results of the evaluation based on regional risk factors, summarized evaluationof the environmental risk assessment and management area specificity anduniversality, in order to verify the feasibility of constructing the applicationevaluation system and management system.
