Control and adjust water flow, flood control, water source development and application construction. Achieve the important purpose of water composition. There are many disciplines involved in hydraulic structures, which are closely related to hydraulics, hydrology, design mechanics, soil mechanics, rock mechanics, structural engineering, engineering geology, building materials and water conservancy survey, water conservancy planning, water conservancy management architecture and water conservancy management. Its design and research methods, main theoretical analysis, testing, observation and comparison of prototype projects.
The main characteristics of hydraulic structures are: natural conditions, topography, geology, hydrology and meteorology are very important in building site selection, construction general layout and project investment. (2) complicate the working environment, for example, the water-retaining structure bears a lot of pressure and seepage from the building strength and stable negative osmotic pressure; The sluice discharge structure has a strong role in correcting the erosion of river bed and river bank. (3) The construction is difficult, and the quality problems need to be properly solved during the period of building conversion, closure and capital construction. In addition, the ground engineering is complicated, and the construction technology of underground engineering and underwater engineering is more complicated. Blocking the flood of structural accidents will bring huge losses and disasters and reduce the accessible distance.
