The wharf engineering primarily serves as protective structures, consisting of foundations, walls, and roofs, which must be sturdy and stable during construction. Wharfs commonly reinforce their bases with pile driving or the use of wooden cribs. Large, solid stone blocks are chosen for masonry, and sometimes, a widened loess layer is used as the foundation, upon which the wharf is built. Wharf engineering is constructed at the edge of bodies of water and the intersection with land, using engineering methods to process and stabilize the shore, preventing damage from various natural and human factors, and protecting the facilities of scenic gardens and water bodies.
