摘要

    摘要
  • 摘要: 半直立式圆筒护岸是一种新式港口工程结构，结合其在大连某水工护岸工程中的应用，进行了半直立式圆筒护岸地基的加载试验，通过实测土压力、沉降、水平位移及孔隙水压力，分析了半直立式圆筒护岸地基的沉降及水平位移变化特点，并进一步研究了其不均匀沉降的发展过程。试验结果表明：半直立式圆筒护岸沉降及水平位移对护岸荷载分级、每级荷载加载量、加载历时及两级荷载之间的间隔时间较为敏感，其中护岸后方最后一级不对称加载对圆筒结构的不均匀沉降影响最大，孔隙水压力变化主要受每级加载量、加载历时及潮汐作用影响，而圆筒安装及第一级荷载施加后，孔隙水压力产生较大的波动。
    Abstract: Semi-vertical cylindrical revetment is a new port engineering structure. Field load tests on a semi-vertical cylindrical revetment is carried out based on its application of a hydraulic revetment in Dalian. The earth pressure, foundation settlement, horizontal movement and pore water pressure of the semi-vertical cylindrical revetment are monitored. The settlement and horizontal movement of foundation of the semi-vertical cylindrical revetment are analyzed, and its non-uniform settlement is further studied. The monitoring results indicate that the sensitive factors affecting the settlement of the semi-vertical cylindrical revetment are loading stage, loading intensity, loading duration and loading intervals. The final unsymmetrical loading behind the revetment has the greatest impact on the non-uniform settlement of cylindrical structure. The variation of pore water pressure is mainly affected by each loading, loading duration and tidal action. When the cylindrical structure is installed and the first level of loading is applied, there is a remarkable fluctuation of pore water pressure.
