Study On The Construction Security Risk Early-Warning Management System For Baitao Tunnel Group

The highway mountain tunnel construction security is an important constituent of safe engineering,Because of the complexity of the mountainous highway tunnel construction and professional,mountain highway tunnel geological environment,and safety technical measures will be all aspects such as influence of mountain highway tunnel construction safety risk factors,these factors is complex and have uncertainty.How to carry out scientific analysis and mountain highway tunnel construction safety risk early warning management,reduce the loss from the risk,and enhance the social efficiency or the economic efficiency is a problem which need to solve urgently.Based on FuLing BaiTao tunnel group engineering in this paper,based on the information concerning the tunnel design and construction,combined with domestic and foreign research results for highway tunnel construction safety and warning,USES the analytic hierarchy process(AHP)and fuzzy synthetic method,systematically discusses the construction risk management and early warning system for tunnel group question research,main research contents and results are the following:(1)both at home and abroad were introduced in detail to the problem of highway tunnel in risk;(2)fully discusses the BaiTao tunnel group of engineering geological environmental conditions;(3)through BaiTao tunnel group of site construction monitoring data,such as system analysis the BaiTao tunnel group of the types and the causes of main construction risk;(4)with field investigation,literature collection and indoor analysis,the method of characteristics for BaiTao tunnel group,study and formulate the BaiTao tunnel group of main treatment measures of the construction risk and the corresponding construction technology;(5)detail tunnel warning related theory,constructs the Bai Tao group of tunnel construction risk early-warning index system;(6)the study of early warning methods and processes,set up BaiTao group of tunnel construction risk early-warning system,determine the early warning level warning limit and warning;(7)the fuzzy synthetic method to establish BaiTao tunnel group of construction risk early warning model,and using the analytic hierarchy process(AHP)to calculate weight of early-warning index;(8)using Delphi software tools,the establishment of BaiTao group of tunnel construction safety risk early warning management system for computer aided system,analysis the tunnel construction safety state;Main innovative points of this article is :Building a system of warning indicators for the construction of a cluster of white tao tunnels;The relevant construction risk alert software system is developed.Using the Delphi software tools to design computer aided system,it can be more accurate early warning analysis of the karst geology of BaiTao tunnel group,dynamic management,fixed early warning index weight and the risk evaluation set,with higher flexibility accurately,real-time early warning.The research results and the research methods used in this paper has certain theoretical guidance meaning and practical value for tunnel engineering construction.
