Abstract


The construction industry is the pillar industry of China's national economy, the construction industry healthy development of China's socialist market economy, the development of the national economy has a crucial role. Production safety in the construction industry has long been plagued by the problems of the industry and the majority of scholars. Particular, with the rapid development of China's economic construction, construction industry by leaps and bounds in recent years, the construction safety accidents have repeatedly occurred in the annual construction safety accidents number of construction safety accident death toll rising trend. Government leaders at all levels in China has always attached great importance to the issue of safety in production, the relevant government departments have also taken a lot of policies and measures. However, these policies and measures, still can not effectively curb safety accidents occur frequently, which can not cause us a profound reflection taken in our current production safety management system. Based on certain safety science methods and procedures, as well as the corresponding safety regulations, regulations, standards, on the basis of full investigation and study, analysis of all aspects of the safety factors in the construction process, the security situation of the construction, so as to develop The safety assessment and early warning provides a scientific basis. Comprehensive utilization of safety system engineering, computer software engineering theory and advanced technology, in-depth, systematic research on the safety assessment and early warning in order to establish a construction safety warning model based on support vector machine. The main contents are as follows: in the study of the current situation and existing problems of China's construction industry safety management, safety in construction management experience of developed countries in the world, building construction safety evaluation and early warning analysis of the current situation in China, the necessity and urgency. 2 from the system to establish and quantification of the system structure and other aspects of safety evaluation framework - Establishment of safety evaluation criteria were studied. Three pairs of support vector machine theory on the basic concepts introduced and explored in depth the basic theory of SVM algorithm. Then carried out further in-depth study of two specific SVM algorithm and LS-SVM algorithm. 4 support vector machine security early warning mechanism and support vector machine used in the security warning. 5 summarizes the research work, prospects for future research.
