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.
