The Stress and Displacement Analysis of the Cut-Off Wall for the Deep Overburden Dam Bo Zhang Department of civil Engineering & Architecture, Shaanxi University of Technology, HanZhong, Shaanxi, 723001, China zhangyc_2005@126.com Keywords: Cut-off wall, Deep overburden, Clay core, Stress and displacement.
Stress and Displacement Analysis of the Cut-Off Wall The horizontal displacement, vertical stress, and stress level distributions of longitudinal section of the cut-off wall are given from figure 2 to figure 4 in engineering completion period.
Comparing with engineering completion period, the horizontal displacement of the cut-off wall increases to 5.9cm in the downstream direction for the water load action, but the vertical stress decreases and the maximum vertical stress is 21.6MPa because the cut-off wall has lager lateral deformation.
