Application Of Disaster Warning System In Monitoring Of Yiyang Tunnel Construction

With the development of China's economic construction,infrastructure project construction in the panorama spread out across the country,engineering geology,design,construction and operating the construction of the geotechnical engineering problems such as more and more,the corresponding engineering disasters are more frequent,if to assure the safety of construction operations and reduce losses of life and property is more and more concern of the engineering.Face the occurrence of geotechnical engineering in complex geological environment object,for unforeseen environmental disaster geological defects(rain)extreme condition,etc.,engineering disasters unexpectedly,thus how to disaster early warning,even forecast disaster become geotechnical engineering disaster prevention and control of key scientific problems to be solved and the engineering problem,this paper work mainly for engineering applications of the field application and solution of engineering problems.Yiyang southern paper using automatic monitoring technology to project binjiang road tunnel project construction period and the surrounding environment(slope and important building,etc.)to carry out the reasonable and effective early warning forecast,the automatic monitoring and early warning method to ensure the construction safety,for the similar engineering problems related to the support and application cases.The main research work and conclusions are as follows:1.Yiyang southern binjiang road tunnel project by project data summary and combined with drilling and geological reconnaissance,analyzes the geological environment and engineering environment project,for disasters may occur in the project construction process problems and important buildings and in selecting the monitoring equipment automation,on the basis of considering construction process,cycle developed automation monitoring implementation plan;2.On the basis of the preliminary research of the project team,the project's automatic monitoring,warning,analysis and prediction standards were established by taking displacement and change rate as the engineering risk control indicators and combining with the safety control standards of tunnel construction design.The automatic warning and prediction platform was used to realize the automatic warning and prediction of engineering risk.3.Relying on the automatic monitoring during construction period,for example,analyzes in detail the construction cycle monitoring deformation development process,and studied the early warning index construction disasters occur status of critical deformation and evolution,and through the early warning platform timely warning forecast,to ensure the project in the period of construction engineering and personnel safety.
