摘　　要：板桩墙的入土深度和内力是否准确关系到整个码头结构的稳定性,我国实际工程中板桩码头的内力计算以线性方法为主。以镇江中船重件码头为例,分别用弹性线法、竖向弹性地基梁法以及自由支撑法计算板桩的入土深度。将3种方法的计算结果进行了对比分析,得出不同方法的适用范围、利弊及改进方法,为实际工程的设计提供参考和指导。The structural calculation of the sheet-pile wall is an important factor in sheet-pile wharf, which is a major form of wharf structures. The buried depth of the pile and the precision of inner pressure have close relationships with the stability of the wharf structure.Taking Zhenjiang Zhongchuan heavy cargo wharf for example, we use three methods to calculate the buried depth of pile, including the elastic line method, m method and free support method, while the elastic line method is the most frequently used in practice in China. Eventually, the comparison among the results from three methods can sum up the application range, pros and cons, and improvement suggestions for each method, thus provide reference and guidance for the actual engineering and design.
