| 摘 要： | 黔中水利枢纽一期输配水工程杨家坝渡槽单孔跨度50m,是国内最大跨度的渡槽。在风荷载等作用下的侧向稳定是关系到建筑物安全的重要指标。采用ANSYS有限元软件模拟地基条件和渡槽在复杂荷载作用下的工作情况,进行了渡槽整体侧向稳定验算,包括槽身在槽墩支座的剪切滑移稳定性和渡槽整体沿基础面的抗滑稳定性以及地基承载力。结果表明,渡槽的整体侧向稳定和地基承载力均满足要求,为杨家坝大跨度预应力渡槽经济安全设计提供了重要参考。

| Abstract: | Yangjiaba aqueduct is a part of Guizhou Water Control Project whose single span is as long as 50m,it is a large-span pre-stressed aqueduct.Affected by wind loads,lateral stability is an important index relating to the safety of buildings.ANSYS is used to simulate foundation conditions and aqueduct under complex load to check the whole aqueduct's lateral stability,including the shear-slip stability between the aqueduct body and bearing,the anti-skidding stability between the whole aqueduct and the foundation... |
