摘要
山东黄前水库粘土心墙土坝采用劈裂灌浆技术加固．本文根据Ｂｉｏｔ固结理论，利用有限元方法对坝体的变形和应力状态及坝轴线附近劈裂缝的变形进行了计算分析，并与现场实测资料比较．计算中对坝体土料的应力应变关系采用椭圆——抛物双屈服面弹塑性模型，以反映坝体劈裂灌浆加荷的复杂性．
The stress and deformation of Huangqian Earth Dam with clay core during splitting grouting are analysed by FEM based on the Biot consolidation theory, and comparison of the results and in situ observations is made. An elasto plastic stress strain model for soil with ellipse parabola curved yield surfaces is used to describe the loading complexity in splitting grouting.
