摘要
以上海老港填埋场四期工程为背景,利用通用有限元软件对填埋场的动力响应特性进行三维数值模拟分析,研究填埋体堆载高度、填埋体边坡坡度、填埋体平面尺寸对填埋场动力响应的影响,得出填埋场在不同填埋体形态下的动力响应规律。计算结果表明:对同一填埋场而言,填埋体测点动力响应随其标高增大而增大。随着填埋体堆载高度的增大,填埋体动力响应逐渐增大。填埋体边坡坡度的变化对于填埋体的动力响应影响较小。
Laogang landfll phase IV project is the background of this article, three dimensional numerical simulation analysis on dynamic response characteristicsof landfillis conducted by using general finite element software, effects of the filing height, slope angle and plane dimension of the waste landfill on its dynamic response are analyzed, and dynamic responses of the landfills with different configurations are obtained. The results show that dynamic responses of measuring points of the waste landfill increase as elevations of the measuring points increases for the same landfll. Dynamic the filling height. Change of the slope angle hardly affects responses of waste landfill increase with increase of dynamic responses of the waste landfill.
