城市外环立交桥施工组织及其质量模糊综合评价研究

Research on Fuzzy Comprehensive Evaluation of Construction Organization and Quality of Urban Outer Ring Overpass

摘要:

城市外环立交桥施工需在有限时间内完成，传统质量评价方法难以满足实时性需求，为实现对施工质量的快速、准确评价以便及时发现问题并采取措施，提出了一种城市外环立交桥施工组织及其质量模糊综合评价方法，能将施工组织分为施工计划、资源分配计划、风险管理计划、技术方案、安全管理以及质量控制这几个方面，据此构建施工质量模糊综合评价体系，建立一级模糊评价的高斯隶属度函数以完成质量二级综合评价。实验结果表明，研究方法下的Kendall协调系数始终高于0.9，这说明该方法的施工质量评价结果符合实际情况，具有较强的应用性，可有效对城市外环立交桥施工质量进行实时监控与评价，有助于及时解决施工中的质量问题并确保施工进度。

Abstract:

The construction of urban outer ring overpasses needs to be completed within a limited time, and the traditional quality evaluation methods are difficult to meet the real-time requirements. In order to achieve the rapid and accurate evaluation of construction quality so as to timely identify the problems and take measures, a fuzzy comprehensive evaluation method for the construction organization and quality of urban outer ring overpass is proposed to divide the construction organization into construction plan, resource allocation plan， risk management plan， technical scheme, safety management and quality control. Based on this, a fuzzy comprehensive evaluation system for construction quality is established. A Gaussian membership function for the first level fuzzy evaluation is established to complete the second level comprehensive evaluation of quality. The experimental results show that the Kendall coordination coefficient under the research method is always higher than 0.9, which shows that the construction quality evaluation results of this method are in line with the actual situation and have the strong applicability, can effectively monitor and evaluate the construction quality of urban outer ring overpasses in real time, and helps to solve the quality problems in construction in time and ensures the construction progress.
