“…However, as a typical water transportation project, the construction of a high-pile wharf involves aerial work and underwater work. The prefabrication, transportation and installation of large components for the project involves a wide range of construction materials and machinery, which brings more and more huge challenges for the construction safety management of the project [2]. In particular, the wharf construction is usually located in the offshore and open sea area, which is greatly affected by meteorological disasters and has very complicated geological conditions [3].…”

The complexity of the wharf components and the harshness of the offshore construction environment increase the safety risk of hazards, which has highlighted the importance and urgency of safety risk management in high-pile wharf constructions. This paper established a visualized digital construction safety risk model for high-pile wharf based on a so-called FAHP method (the combination of fuzzy comprehensive evaluation (FCE) and analytic hierarchy process (AHP) methods). The construction safety risk indicators were constructed as the target layer, the principle layer and the scheme layer, and then the corresponding safety risk assessment algorithm was established. The physical, functional and safety risk assessment parameters of the component in the BIM model were employed to the safety risk assessment algorithm, and the risk assessment level of each sub-process was subsequently classified. The case study indicated that the high-pile wharf construction project included five elements in principle layer and 15 risk indicators in the scheme layer. Moreover, it was demonstrated that the sub-processes with the highest construction risk level were steel pipe pile sinking in wharf construction and steel pipe pile, steel sheath-immersed pile sinking and embedded rock pile construction in approaches to bridge construction with a risk level of III. In this way, the quantitative visualization of the construction safety risk was effectively realized, which facilitates the safety risk management of construction sites and timely warning and response to unexpected safety accidents.

“…In terms of the engineering theory, Manna et al [13] explored the impact of nonlinearity on the dynamic response of cast-in-situ-reinforced concrete piles subjected to strong vertical excitation. Beyond that, Su et al [14] proposed a disturbing-energy method for the safety assessment of high-piled wharves based on the variational principle and minimum potential energy principle. Then, Zheng et al [15] proposed an analytical framework for the horizontal dynamic analysis of a large-diameter pipe pile subjected to combined loadings, which provided appropriate estimates of complex impedances of large-diameter pipe piles.…”

In the long-term service, the wharf structure can be damaged by ship impact, wave load, and even earthquake, which will affect the safe production and smooth operation of the port. Based on the theory of structural dynamic response analysis and wavelet packet analysis principle, this paper established the damage identification index of the wharf frame structure. Combining with the finite element method and the dynamic response theory of the wharf frame structure, it set up a finite element analysis model of the dynamic response of the wharf frame structure under the action of multiple loads, with the impact load of the ship as the dynamic load under the non-damaged state and the different damaged states. In addition, the characteristic response point location was drawn up. Furthermore, the transient dynamic analysis and damage index analysis of the frame structure in the non-damaged and damaged state were conducted respectively. In addition, the model test and numerical simulation results were combined to compare and analyze the identification of damage indicators, so as to verify the identification effect of the established damage identification indicators on the structural damage, which lays a foundation for the next step of structural damage identification.

“…With the development of larger ships, pile-supported wharfs are subjected to a greater number of lateral loads, and thus, more batter piles are needed. At present, the optimization of pile groups involving batter piles focuses on their bearing capacity and di erential settlement [15][16][17][18][19]. In addition, pile foundations may intersect spatially, resulting in failure of construction.…”

The pile-supported wharf is widely used in port wharf design due to its excellent adaptability. However, it may intersect in space because a large number of batter piles are used. In the design process of the pile-supported wharfs, pile orientation adjustment is an essential process to avoid pile intersection. The arrangement of pile orientation in a structural section often takes several days manually. Sometimes, designers cannot avoid pile intersections after many attempts. At present, the software can only check pile intersections, but it cannot optimize pile orientations. Considering the priority order of adjusting the pile slope, the rotation angle, and avoiding a pile intersection, the objective function for optimization is designed, and the pile orientation is optimized and adjusted by a genetic algorithm. Then the performance of the algorithm is analyzed. Finally, the algorithm is applied to two practical cases of pile-supported wharfs. One case involves the designers who failed to arrange the pile orientation. Moreover, satisfactory results of pile orientations are obtained in a few minutes. Therefore, the proposed method greatly improves labor efficiency.
