摘要
城市内的地铁隧道,一般都选择在道路下穿行,因此,不可避免地会对城市道路路面造成破坏.分析了路面由于盾构施工造成的多种破坏类型,讨论了路面寿命周期内费用组成,并采用公路沥青路面使用性能评价方法和标准,建立了由于盾构施工导致沥青施工路面出现最大沉降量与其使用性能指标和费用损失之间的风险评估模型,并进行了模型应用研究.
Generally, subway tunnels in soft soil area are built under the pavement. Therefore, it is inevitable that the urban roads are often damaged and broken during the shield tunnel construction. This paper analyzes the different breakage types due to shield tunnel construction, discusss the cost composition of the road in its whole life, and then establishes a risk evaluation model on three parameters such as the maximum settlement, pavement performance and cost loss for urban asphalt roads. In the end, a case study is conducted.
