为了对桥梁建设方案进行多目标的风险评价,利用信息熵的原理建立评价模型,得出评价结论,验证该方法的实用性。通过分析桥梁建设阶段的风险特点,确定风险评价目标,运用信息熵的原理从量化的角度出发,对建设方案进行包含美学目标的多目标的风险评价,依据贴近度和差距值对建设方案进行风险排序。此方法可以在不依靠专家权重的基础上做出合理的风险评价,并指导方案的优化选择,不仅说明了该方法的实用性,更为业主对桥梁工程的风险管理提供了新的思路。
In order to carry out the multi-objective risk assessment of the bridge construction scheme, the evaluation model is established based on the principle of information entropy, and the conclusion of the evaluation is obtained to verify the practicability of the method. By analyzing the characteristics of risk during the bridge construction phase and determining the risk assessment objectives, the information entropy principle is used to carry out the multi-objective risk assessment of the construction project from the perspective of quantification. The risk of the construction project is determined according to the closeness and the difference value Sort. This method can not only rely on the expert’s weight to make a reasonable risk evaluation, and guide the optimization of the program, which not only shows the practicality of the method, but also provides a new idea for the bridge project risk management.
