摘要
Abstract
Based on the concrete cutoff wall schemes in a reinforced unsafe clay core earth⁃rock fill dam, the typical section was calculated with numerical simulation method. In this paper, it studied the stress and deformation variation of concrete cutoff wall and dam, compared the performance differences of the three different elastic modulus plastic walls with the rigid wall and the impact of the plastic concrete cutoff wall material on stress and deformation. The results indicate that the stress distribution of plastic wall is homogeneous and the compression stress, tensile stress, shearing strength are all much less than that of rigid wall; the deformation between plastic wall and dam body is well coordinated, the deformation between rigid wall and dam body is large which increases the wall stress. The stress and deformation characteristic of plastic concrete wall are much better than that of rigid concrete wall.关键词
