摘要
近年来,全国各地道路地面塌陷事故频发,造成了严重的经济损失与人员伤亡,已成为影响城市公共安全的焦点问题。利用上海市道路地面塌陷案例数据,系统分析城市道路地面塌陷主要成因及影响因素,建立城市道路地面塌陷评估指标集及计算模型。结合选定的上海市杨浦区、长宁区和闵行区等3个区域部分道路开展应用,利用历史案例数据和评估结果以及近期浦东新区实际案例,验证该指标体系的适用性及评估模型的准确性。研究工作可为上海城市道路地面塌陷评估与精细治理提供理论模型和实践指导,并为其他城市道路基础设施韧性安全提升提供技术参考。
In recent years,frequent road surface collapse incidents have occurred nationwide,causing significant economic losses and casualties,becoming a focal point in urban public safety concerns.Based on the collected case data of road collapse happened in Shanghai,the main causes and influencing factors of urban road collapse is analyzed systematically in this paper,and the evaluation index set and calculation model of urban road collapse based on entropy weight method is established here.Then,the selected area in Yangpu,Changning and Minhang of Shanghai is applied the model in combination with some typical roads,and validified the accuracy of its index system and evaluation result by using historical case data,evaluation conditions and recent accident in different regions,which can provide a theoretical model and practical guidance for the assessment and fine management of urban road collapse in Shanghai and other cities for their resilience and safety of road infrastructure.
