Regarding the increasing variety and quantity of pipelines at the comprehensive wharf and the growing difficulty in pipeline laying，a new type of trench structure design is proposed.This design facilitates the laying and maintenance of multiple pipelines，while meeting the requirements for pipeline layout and personnel access.By introducing holes at the front and rear edges of the traditional transverse beams and laying longitudinal beams in the trench，a spatial system is formed that runs below the wharf surface，allowing for the utilization of the double-deck function of the high-pile beam slab wharf.The three-dimensional solid element modeling using Midas Civil calculation software is employed to calculate and analyze internal forces.The results show that the internal forces in the transverse beam structure meet the standard requirements.Additionally，a comparison between the horizontal distribution coefficient of the wharf structure and the standard distribution coefficient shows that the data is basically consistent，ensuring the rationality and safety of the lateral force distribution of the support frame.This structural design can serve as a reference for similar types of wharves.
