Seismic-resistance Analysis Of Sluice

Sluice is a kind of water hydraulic structures with low head.It is widely used in water constrction for it's function of water retaining and sluicing. It is mainly used to control the water flow and adjust the water level.It is also take in charge of the flood discharging and preventing pollution of the flood.Earthquake breaks up frequently in recent years,it makes a big threat to the country and the people's property security. The security of sluice is relation to the local peaple's safety. The investment of a sluice is very big, once it damages seriously, not only endangers the project safe itself, it also produces a chain reaction and cause secondary flood, the loss caused by secondary disasters often exceeds the loss caused by the quake itself. The security of Water conservancy engineering anti-earthquake has special importance.In engineering ,The anti-seismic analysis of sluices mostly using an equivalent method based on rigid static or dynamic method based on the simplified calculation method, these methods are simply but not accaratly enough to reflect the common interaction of foundtion ,water and sluice. Especially for establishment in soft soil and weak interlayers foundation.Using the three-dimensional finite element analysis software ANSYS make a static analysis of TianKou Sluice. the main contents is : Make a whole modal of sluices and foundation; do research in the displacement of fountion and stress and strain of sluice in different periods;Study the application of Housner in earthquake calculation method of spatial sluices; Using the ANSYS program, study the gate vibration modal in different conditions; Using the method of dynamic analysis, study the earthquake damages in different direction under the dynamic stress, get the displacement map of sluices at different stages of the time ; Make an analysis of the data and image ,and then do research in the stress and strain condition of sluice, verify the safety design of the sluice.
