Resaerch On Comprehensive Assessment Of Occupation Health Status In Tunnel Construction And Countermeasures

Although the construction industry has popularized the occupation health safety management system certification, but due to the security characteristics of the tunnel construction industry, occupation health management has always been the weak link in the tunnel engineering because of the relatively confined space, especially the situation of the drilling and blasting construction of the tunnel is not optimistic. According to the spirit and requirements of "On how to launch the activities of the year of the workplace occupation health supervision and law enforcement"(2014 Sichuan Anjian Letter No.23) published by the Administration of Work Safety of Sichuan Province, this thesis uses the method of the actual survey, have a comprehensive grasp of occupation health status of Sichuan Province tunnel construction enterprises, further study of the occupation.health conditions of tunnel enterprise comprehensive evaluation by fuzzy evaluation method, on the basis of the evaluation results to put forward the countermeasures of economic applicable.First of all, systematically study the theoretical basis of the field survey and detection of occupation health.Through analyzing the occupation health status of China, Sichuan Province and the key industries and key areas of Sichuan, aware of launching the research of the occupation health status of Sichuan Province tunnel construction enterprises is very important.Thus further study occupation health knowledge, Make the plan of the research, master the field investigation and detection skills,make full preparations for the survey and detection of the scene.Secondly, lanch the occupation health investigation and detection, obtain the first-hand technical information.Choosing 4 seat on-builtting tunnels in Sichuan Province as the research object, deepen into the work site to lanch the occupation health survey and detection of harmful factors.Complete chemical analysis in laboratory to obtain results timely, then sort out and analyze the results of data and information.Then, using the fuzzy evaluation method for the comprehensive evaluation of the tunnel construction occupation health.Discarding simply comparing the concentrations (strength) of individual occupation hazards to limiting value, and the conventional evaluation method of compliance the relevant prevention and control measures with occupation health laws and regulations standard.Creatively introducing the fuzzy evaluation method to comprehensive evaluation the occupation health status.Comprehensive consideration of various factors in the operating system impaction on workers health, effective evaluation of the comprehensive risk level of occupation disease harm in the workplace, and systematically grasp the occupation health conditions of the tunnel construction.Finally, proposing targeted countermeasures to effectivly manage the occupation hazards in tunnel construction. According to the occupation health status survey results of Sichuan Province tunnel construction, combined with the comprehensive risk level determined by fuzzy evaluation method, proposing a series targeted comprehensive countermeasures which is effective and can be applied to the work site.
