| 摘 要： | 根据江阴大桥南锚碇基础接触应力近百次的观测资源，揭示了层状岩层地基上大跨径悬索桥重力式嵌岩锚基础接触应力在施工及营运阶段的变化规律。实测结果表明：不同施工阶段，锚碇基础不同部位接触应力呈现出不同的变化特征，锚碇运行处于安全状态。

| Abstract: | According to about one hundred contact stress observations of south anchor foundation of Jiangyin Yangtze River Bridge, the changing rule is expounded which is the contact stress of the gravity anchor foundation embedded in layered rock of large span suspension bridge during construction and working. Observational outcome indicates that the contact stress in different parts of anchor foundation presents different changing characteristics in different construction periods, and the working status of the anchor is safe. |
