①There are many constraints imposed by natural conditions; factors such as topography, geology, hydrology, and meteorology have a significant impact on the location selection for projects, the choice of building types, construction processes, the layout of facilities, and project costs. ②The working conditions are complex; for example, water retention structures have to withstand considerable water pressure, and the seepage pressure generated by seepage is detrimental to the strength and stability of such structures ； When water discharge structures release water, they have a strong erosive effect on the riverbed and riverbanks. ③ The construction is challenging; building water conservancy projects in rivers requires proper handling of construction diversion, river closure, and flood control during the construction period. In addition, the treatment of complex foundations, as well as the construction techniques for underground and underwater projects, are also quite complex. ④The failure of the retaining structures in large-scale water conservancy projects can cause tremendous losses and disasters downstream.

Characteristics of hydraulic structures: 1. Complex operating conditions: self-weight, wind and snow loads, seismic effects, water pressure, wind and waves, etc. 2. Difficult construction: (1) Construction in remote areas: deep mountains and forests, no water or electricity, difficult living conditions. ⑵Solving the issue of water inflow into rivers: diversion, interception, groundwater, etc. ⑶Foundation treatment: rock excavation, tunneling, complexity of the foundation. ⑷Massive scale: large volume of work, long construction period, and susceptibility to climate conditions.
