Research On Accident-causing Factors And Countermeasures Of Excavation Engineering

As our country’s high speed development and improvement of the living environment ofpeople, a large municipal constructions were builded and the exvacation is appeared largely.The rate of excavation engineering accidents in our country is higher as the variouscomplicated reasons. Excavation engineering accidents not only cause great loss of people’slife and property, but also has a bad influence to society. It has important practicalsignificance to strength the safety management of exvacation engineering and reduce the rateof excavation engineering by analysing systematiclly the various factors and the possobility ofexcavation engineering accidents and putting forward the corresponding managementmeasures.Firstly, this paper used the related achievements from domestic and international forreference, and combined with China’s excavation engineering’s actual situation proposedexcavation engineering accident-causing theory which suitable for our country’s excavationengineering. Secondly, this paper summerised the accident-causing factors of excavationengineering including construction unit management factor, investigation factor, designfactor, construction factor, supervision factor, monitoring factor by analysing of272casesof excavation engineering accident. And then established the measurement index system. Itanalysed the weight of every factor by the expert scoring method, analytic hierarchy process(AHP) and DEMATEL method to determin the final measuaement index system andestablished the conceptual model of excavation engineering’s accident-causing factors; onceagain, the paper based on the determined index system of accident-causing factor ofexcavation engineering draw up the excavation engineering accident-canse factorquestionnaires and used SPSS16.0software to test the reliability and validity of the reclaimedeffective questionnaires, then fited and explained the preset model by the AMOS7.0software; At last, the paper propsed the safety management which suitable for our country’sexcavation engineering according the empirical results. Through this research, excavation engineering’s accident-causing factors weredetermined. And they can make a comprehensive reflection about our country’s excavationengineer situation. And it is good for the enterprise to put forward some reform measures, soas to promote the safety management level of excavation engineering.
