Three-dimensional Simulation Analysis of Earth and Rockfill Dam Stress-strain over Deep Covering Layer

  • 摘要: 以有限元方法为基础,对新疆吐鲁番二塘沟水利枢纽工程的土石坝进行了三维仿真计算,并对堆石体和心墙在竣工期和满蓄期的应力应变极值进行了分析。分析结果表明,该土石坝的设计是合理的,堆石体和心墙不会发生拉压破坏或剪切破坏;心墙底部向两侧发生大约7 cm的轻微侧胀,成为比较危险的部位,在设计和施工中应予以高度重视。
    Abstract: In this paper,it conducts the three-dimensional simulation calculation on the earth and rockfill dam of Ertanggou hydro-project in Sinkiang Turpan based on the finite element method,and analyzes the stress-strain extreme values of rockfill body and core-wall after the completion period and full storage period.The result shows that the design of the earth and rockfill dam is reasonable,the rockfill body and core-wall won’t appear tension-compression damage and shear failure.At the bottom of the core-wall,it appears about 7cm slight inflation towards to both sides and which makes it become the dangerous place.So we should pay more attention to the design and construction process.
