内河大水位差重力式码头库岸一体化模式分析

结合重庆奉节宝塔坪旅游码头工程的安全评估和加固方案研究．对库区大水位差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。进而计算模拟了库岸的施工过程和水位陡降时库岸的安全系数发展规律。得到了内河大水位差重力式码头库岸破坏模式以及结构安全性指标。

Study of The Stability of Overhead-erection Water Terminal in Reservoir Area

The stability of bank slope of overhead-erection water terminal is discussed according to the safety.assessment and strengthening scheme research of habour engineering at Baotapin, fengjie in Chongqing. 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 is obtained and the pore water pressure is calculated. Meanwhile, the construction of bank slope is analogued and the law of development of assurance factor in the condition of dropping water height. The damage module and structural safety data of bank slope of overhead-erection water habor in reservoir area are obtained.
