摘要
利用通用有限元软件ADINA对在相同荷载下土工格栅加筋高陡坡土石坝与未加筋土石坝两种工况下σ(应力)-ε(应变)状态进行了对比分析,通过数值模拟结果可以看出,土工格栅加筋图高陡坡土石坝与未加筋土石坝相比不仅ε(应变)明显减小,而且σ(应力)也相对减小。实例应用表明,加筋土工格栅使用在土石坝中,不仅使得坝体的建设不再受到地形的限制,而且是一种实用有效的方法。
The general finite element software ADINA is used to compare the 滓 （stress）-着 （strain） state of reinforced high steep slopeearth rock dam and unreinforced earth rock dam under the same load. It can be seen from the numerical simulation results that thereinforced high steep slope earth rock dam not only has a significant decrease in 着 （strain） but also a relatively small 滓 （stress） comparedwith the unreinforced earth-rock dam. The application of the reinforced geogrid in the earth-rock dam not only makes the construction ofthe dam no longer limited by the terrain, but also is a practical and effective method.
