采用测量、开挖等方式对佛开改扩建工程西二环连接线路面裂缝病害进行现场调查,路面裂缝呈现面层基层贯通、沿行车道距路侧边坡2～6m位置连续分布等特点。模拟病害路段附近匝道填土情况,建立路基竖向应力计算模型,计算病害路段地基土中不均匀分布的竖向应力,分析了路面裂缝病害形成的原因。
採用測量、開挖等方式對彿開改擴建工程西二環連接線路麵裂縫病害進行現場調查,路麵裂縫呈現麵層基層貫通、沿行車道距路側邊坡2～6m位置連續分佈等特點。模擬病害路段附近匝道填土情況,建立路基豎嚮應力計算模型,計算病害路段地基土中不均勻分佈的豎嚮應力,分析瞭路麵裂縫病害形成的原因。

By measuring and excavating, site investigation on the pavement crack disease of the Connection Line of Fokai Extension Project with Xi'erhuan Expressway has been carried out. The pavement crack appears such several characteristic as penetrating base layer, distributing along the driving lane 2 - 6m away from roadside slope. With soil filling of ramps in the disease area being simulated, the embankment vertical stress calculation model has been established, and the uneven distributed vertical stress in disease area has been calculated, the cause of the pavement crack disease has been analyzed.
