TL;DR: In this paper, a three-dimensional mathematical model is established to simulate the deformation trend of a high piled wharf structure with bank slope soil under unbalanced load condition, and the results show that the pile cap plays a positive role in the stability of the wharf slope.
Abstract: After a large-scale construction period, there are a large number of old high piled wharfs in China's ports. The pile cap piles and beam members of some wharfs close to the earth retaining structure appear obvious dislocation, and some of them are increasing year by year. In this paper, the typical section of Tianjin Port 16 ~ 18 wharf is taken as the research object, and a three-dimensional mathematical model is established to simulate the deformation trend of wharf structure with bank slope soil under unbalanced load condition. The results show that the pile cap plays a positive role in the stability of the wharf slope. Partial load can cause the deformation of soil along the bank. The horizontal earth pressure acting on several rows of piles behind the pile cap is large, which leads to large deformation and internal force of the pile body. When the force between the pile top and the beam exceeds the lap strength between them, the pile top and beam will be staggered. The fundamental method to avoid or improve the seaward movement of high piled wharf and bank slope is to block or reduce the horizontal earth pressure from the rear storage area to the front. The scheme of sheet pile wall or bored pile can be selected according to the actual situation.

TL;DR: In this paper, two-and three-dimensional finite element analysis programs for pile-soil interaction are compiled and the construction sequence of a pile-supported pier is modeled, and the influence of the combination type of piles on the deformation of bank slope and pile behaviour is analyzed.
Abstract: Two- and three-dimensional finite element analysis programs for pile-soil interaction are compiled. Duncan-Chang's Model is used. The construction sequence of the pier is modeled. The pile-soil interface element is used. The influence of the combination type of piles on the deformation of bank slope and pile behaviour is analyzed. Different designs of a pile-supported pier are compared thoroughly. Calculation results show that the stresses and displacements of the pile are directly related to the distance from the bank slope and the direction of inclination. An inclined prop pile set in the rear platform would remarkably reduce the stresses of piles and the displacement of the pier.
