Safety Evaluation And Research Of The Temporary Structure Of The Bridge Construction

In recent years, in order to meet China’s rapid economic development needs of thetransportation, the cause of our bridge has been rapid development. At the time ofrapid growth has also brought many problems, due to the geographical environment inwhich complex and not fully understood, natural disasters uncertainty large, longerduration, resulting in the unpredictability of the bridge foundation construction risk.The risk factors involved in the bridge construction, including political, social,economic, natural, technological and other factors, to varying degrees, these factorswill act on the bridge construction, intricate impact. Moreover, different risk factorswill have a number of different risk events, so increases the risk probability of thebridge-building process. Event risk events often result in huge losses.Bridge construction safety evaluation focused on the safety assessment of theoverall structure of the bridge, for the safety evaluation of the structure of thetemporary bridge construction process rarely involved. Therefore, the use of riskassessment method in the financial sector, carried out a systematic analysis oftemporary structures for bridge construction safety of construction safety evaluationmodel and application, mainly to do the following work:①Concise exposition of the research status of the bridge construction riskassessment study, analysis of the deficiencies in the bridge construction risk researchand applications.②The introduction of the principle of risk management of the financial sector,detailing the risks that may arise in the bridge construction, grasp the regularity of therisk as much as possible. The characteristics of the bridge construction, bridgeconstruction risk summarized.③Bridge construction risk assessment is conducted on the basis of the riskidentification, detailing the concept of risk identification, characteristics and process ofrisk identification and detailed list of possible risk factors in bridge construction in theconstruction of temporary structures.④The introduction of fuzzy analytic hierarchy process from fuzzy math beginwith AHP and fuzzy comprehensive evaluation wears in combination, to overcome theshortcomings of fuzzy comprehensive evaluation method in the evaluation factors todetermine the subjective evaluation object weight and at the same time have a AHPand fuzzy comprehensive evaluation method has the advantage. ⑤The model of fuzzy analytical hierarchy process to establish to cradleconstruction Bo deep Bridge construction from design to construction, removal of allphases of the risk assessment. Reached the level of risk of the cradle construction, inthe actual implementation and also verified the accuracy of the evaluation model.
