基于改进的层次分析法和接近理想点法的桥梁施工方案风险评价研究

桥梁工程建设具有施工周期长、施工环境差、系统调配复杂、资金流动量大的特点,需要准备大量的施工原料、机械、人力资源.因此,在桥梁施工过程中会面临自然环境、安全施工等多种风险的影响.为保证施工的顺利进行,本文建立了基于改造的层次分析法(Analytic Hierarchy Process,AHP)和接近理想点法(Technique for Order Preference by Similarity to an Ideal Solution,TOPSIS)的桥梁施工方案风险评价模型,通过对风险进行评价研究,提出最优施工方案,以减少施工风险,提高施工效率.

Risk Assessment of Bridge Construction Scheme Based on Improved Analytic Hierarchy Process And Near Ideal Point Method

Bridge engineering construction has the characteristics of long construction period, poor construction environment, complex system deployment and large amount of capital flow, requiring preparation of a large number of construction materials, machinery and human resources. Therefore, the construction will face the impact from natural environment, safe construction and other risks. In order to ensure the smooth construction, this paper establishes a risk evaluation model for bridge construction schemes based on the improved analytic hierarchy process (AHP) and the near ideal point method. Through the risk evaluation and research, the optimal scheme is proposed to reduce the construction risk and improve the construction efficiency.
