摘要
板桩码头计算主要依据现行板桩码头设计规范。为提高计算精度,以某实际工程为例,采用其他两种改进的计算方法对板桩码头结构进行计算,对比各方法在计算模式上的异同点,分析各方法的计算结果。弹性地基梁法计算最重要的参数是水平地基反力系数随深度增大的比例系数m,建议按照土层的粘聚力c、内摩擦角φ确定m值。
The calculation of sheet pile wharf is mainly based on the current code for design of sheet pile wharf.In order to improve the calculation accuracy, this paper takes a practical project as an example and uses the other two improved calculation methods to calculate the structure of the sheet pile wharf. The similarities and differences of the calculation methods are compared, and the results of each method are analyzed.The most important parameter of the elastic foundation beam method is the proportion coefficient m of the horizontal ground reaction coefficient which increases with the depth.It is suggested to determine the m value according to the cohesion c and the internal friction angle φ.
