| 摘 要： | 混凝土重力坝抗滑稳定分析方法较常用的方法是抗剪断安全系数法,该方法忽视了坝体与基岩的应力应变关系,使接触面上的阻滑力与滑动力的计算结果存在一定的误差,导致抗滑稳定安全系数存在较大误差。利用有限单元法,在充分考虑坝体所受到的各种荷载及复杂的地质条件下,计算重力坝与基岩接触面上的阻滑力和滑动力,再利用抗剪断安全系数法对重力坝的抗滑稳定进行计算。得到了更为准确的能反应重力坝抗滑稳定的安全系数。分析结果表明,利用有限元法能够准确计算重力坝与基岩接触面上的阻滑力和滑动力,为重力坝抗滑稳定分析及评价提供了可靠依据。

| Abstract: | The shear-resistant safety factor method,often used in analysis of the stability against sliding for concrete gravity dams,overlooks the stress-strain relation between the dam body and dam foundation,so there exist some errors.The finite element method is used to calculate the sliding-resistant force and sliding force between the gravity dam and its foundation,and the shear-resistant safety factor method is used to calculate the stability against sliding of the dam,obtaining much accurate safety factors,and... |
