高速橋梁工程建設(shè)風險管理研究
[Abstract]:With the rapid development of urbanization in China, the bridge construction projects in various parts of the country are also accelerated. As a municipal construction, bridge plays an important role in relieving traffic jam and facilitating public travel. However, with the construction of bridge projects going on one after another, serious accidents often occur in the process of construction, resulting in significant property losses and casualties, and the social impact is bad. Therefore, it is necessary to carry out risk assessment for bridge construction in order to reduce the probability of accidents. In this paper, the high-speed bridge construction risk assessment as the research object, carried out the following research: 1. This paper analyzes the theory of risk assessment of bridge engineering construction, summarizes its concept, characteristics and principles, and explains the classification of risk factors in bridge construction from the aspects of bridge structure, construction and environmental conditions. 2. This paper analyzes and studies the relevant risk assessment methods suitable for bridge construction, focuses on the analytic hierarchy process (AHP) and the accelerated genetic algorithm (AGA), and points out the shortcomings of these two methods, such as the complexity of the AHP method. Large amount of calculation; Genetic method has slow convergence and poor accuracy. A risk assessment model of high speed bridge engineering based on the combination of AGA,AHP and fuzzy mathematics is proposed. The interference of human subjective factors in the whole process of risk assessment is weakened as far as possible, so that the evaluation results are more scientific and accurate, and the probability of occurrence of risk accidents is reduced to the maximum extent. 3. Taking the A Bridge as the engineering background, the risk assessment model proposed in this paper is used to evaluate the risk. The result of the final evaluation is more scientific and accurate, which shows that the model proposed in this paper can carry out scientific and reasonable risk assessment for the bridge construction, and provide the correct risk reference basis for the participants. This method has high practicability.
