| 摘 要： | 结合重庆某内河架空汽车下河斜坡道码头工程安全性评估和加固方案研究，对码头的库岸稳定性进行了分析。分析中考虑土中水的渗流和土体的变形耦合，求出了在稳定渗流条件下库岸的浸润面，并计算出孔隙水压力。通过分析得到了高填方汽车架空斜坡道桩基的破坏模式、桩内力分布、安全评估策略和加固方案。

| Abstract: | In order to research the security evaluation and reinforcement option of overhead-erection ramp terminal of the impounding water of the three gorges reservoir, a scientific method for analyzing this harbor is presented. The infiltration flow of water in the soil and the deformed coupling of soil are considered. In this paper, the infiltrative plane in the term of infiltration flow was obtained and the pore water pressure is calculated. Then, the failure mode of procedure, stress distribution pattern of the pile and the safety index of overhead-erection ramp terminal was obtained. |
