高桩码头岸坡稳定性研究

高桩码头能获得良好的水深条件,是近岸软土地基上最为常见的港工结构型式。桩基码头的岸坡滑动涉及到码头的整体稳定、影响码头的正常使用,是码头结构安全的"生命线"。影响高桩码头岸坡稳定的不利因素主要包括地质条件、桩基施工、水位涨落以及人为因素,与码头建设、设计、施工、监理及运行管理相关人员需执行码头建设相关法规或者强制性标准,以保证工程正常使用。结合武汉新港阳逻港区码头工程,基于极限平衡条分法校核工程建设及河道水位变化对码头岸坡稳定性的影响,可为国内类似工程提供参考。

Slope Stability Analysis of Piled Wharf

Piled wharf has been considered as the most common form in the offshore soft soil founda- tion. Overall stability and normal use of wharf is overmastered by slope sliding, so the overall stabili- ty of bank is the key of wharf security. Adverse factors of piled wharf slope stability include geological conditions, pile construction, the water level fluctuations and human factors, as a result, related reg- ulations and standards should be performed to ensure the normal use of the wharf. In this paper, the limit equilibrium method is applied to analyse the piled wharf slope stability of Yangluo piled wharf in Wuhan, with the condition of project construction and water level fluctuations.
