采用有限元方法对山东省某调蓄水库工程围坝进行了有限元分析,论证了聚乙烯薄膜垂直防渗槽的位置对坝体应力与稳定的影响.通过分析计算表明,目前设计的防渗沟槽的位置及其回填质量不至于对坝体的安全和运行状况造成很不利的影响,由于坝体的施工和运行一般不会对聚乙烯薄膜造成破坏
Finite element analysis of the dam around a reservoir in Shandong Province is carried out by using the finite element method and the influence of the location of the vertical seepage prevention groove on the stress and stability of the dam is demonstrated.Through the analysis and calculation, The location of the trenches and the quality of the backfill will not adversely affect the safety and operating conditions of the dam and will generally not cause damage to the polyethylene film due to the construction and operation of the dam
