Study On Safety Input Of Construction Engineering And Evaluation Of Safe Management

In recent years,with construction industry developing quickly, the safety is worse and worse. More and more people recognize that safety is a kind of benefits to all the people. As safety benefit has some following characters: indirect, latent, secluded, it can not get desired recognition by some enterprises. In a certain extent it account for more serious safety situation. In this paper, the emphases of safety is precaution, the safety input before and during construction should be taken great attention. And bring forward some methods and ways for safety input, do some research to evaluation of safe management of construction engineering. Firstly, analyses classify and occurring rules of safety accidents of construction engineering in order to control happening of safety accidents more effectively. Loss brought by safety accidents is divided into indirect loss and direct loss. Indirect loss is much more than the direct, this paper analyses both of them. Secondly, make further research to safety input, safety benefit and the relation between input and benefit of construction engineering. Build input index system based on analyses of influencing factors of safety input. Gained the safety benefit of construction engineering as following methods: calculate economic benefits and non-economic benefits respectively; study economic increase contribution ratio of construction engineering safety by Dauglas product function. In order to find out the main factors influencing safety benefit, using grey correlation degree make the correct decision for the direction of safety input. Calculating the most efficiency safety input by regression analysis of cases of construction site. At last, build a safe management evaluation index system of construction engineering adapted to our country. And applying BP Neural Network to evaluating safe management.
