Description
One, technical field:
The present invention relates to the dam architecture advances technology of Hydraulic and Hydro-Power Engineering, particularly a kind of combined multi-arch type steel-structure dam.
Two, background technology:
At present, the main water retaining structure in the Hydraulic and Hydro-Power Engineering has gravity dam, earth and rockfill dam and arch dam.The main feature of various dam types is as follows:
The operating principle of gravity dam is that the skid resistance that relies on the dam body deadweight to produce satisfies the dam body stability requirement, and the compressive stress that relies on the dam body deadweight to produce is offset because the caused tensile stress of water pressure.The dam body section size of gravity dam is big, and material usage is big, and dam body stress is lower, and the strength of materials can not be given full play to.And dam body and ground contact area are big, cause the dam at the bottom of uplift pressure big, unfavorable to dam body homeostasis.
Earth and rockfill dam is the dam that utilizes local material to build up, and dam body will have enough sections could keep stable.And the side slope of earth and rockfill dam and dam foundation stability are the basic assurances of earth and rockfill dam safety.Therefore, the dam body structure must be provided with the good anti-drainage that blends with control seepage flow; Guarantee the stable of dam body, the dam foundation.The unsuitable overcurrent of the dam body of earth and rockfill dam need be provided with special release floodwatering facility, could guarantee the engineering safety operation.
Arch dam mainly relies on the counter-force effect of two sides arch abutment to keep the stable of dam body.Therefore arch dam is had relatively high expectations to landform, the geological conditions of dam site, and is also strict to the requirement of ground.And the arch dam section is thinner, and therefore the dam body complex geometry, requires all to want the force of gravity height of dam to construction quality, dam material intensity and antiseepage.
Three, summary of the invention:
For the cross dimensions that overcomes gravity dam, earth and rockfill dam is big, the strength of materials can not be given full play to, and the construction period is long, invests big deficiency; Remedy the arch dam deficiency not strong, invented a kind of new dam type---combined multi-arch type steel-structure dam the compliance of ground.
