Construction Safety Assessment And Early Warning Research

The construction industry is one of the principle industries of the national economy. And for building the socialism market economy and developing the national economy, it is very important to keep it developing well. But, for a long time, the safety in the process of the constructing has puzzled the people who are engaged in the construction industry and the scholars as a problem. Especially, with the rapid development of national economy, the construction industry has gained amazingly quick development. In recent year, there happened many accidents in the constructing, and the number of the accidents in one year takes on an ascending trend. The state always pays much attention on the management of the safety, and takes many measures to prevent the happening of the accidents. However, the measures can't work efficiently. So we must study the safety management system from a new perspective. In this paper, based on ample researching and study, construction enterprise safety alert system is defined to analyze every type of safety factors and to early-warning the safety status in the construction process according to a certain safety scientific approaches, steps, relevant code, statute, criterion, etc. Thus it can provide scientific evidence for enacting fundamental safety early warning.By synthetically using safety system engineering, computer software engineering theories and advanced technologies, this paper has made a profound and systemic research into safety assessment and early-warning working mechanism. Also, it advanced the comprehensive design framework of Safety Early-Warning Model based on support vector machine. The following are the main study contents.1 While analyzing the present situation of safety producing and safety management and introducing the experience or the safety management in the developed countries, point out imminently to establish a new system of safety management in the construction industry.2 Researched into the framework of safety assessment —Safety Assessment Criteria System in the term of the system foundation and system structural quantifying.3 The basic concept of the support vector machine theory has been introduced and the basic theoretical properties have been gone deep into discussed. Then two classical SVM algorithms and LS-SVM algorithm have been done more research.4 This paper studied Support Vector Machine's (SVM) working mechanism in safety early warning, and applied it to safety early warning.5 Last section draws a conclusion from the whole research and takes a look into the forth-coming work.
