本文介绍了防渗墙接头大比尺模型试验，量测了混凝土防渗墙内的应力、廊道与防渗墙之间的相对位移以及填土表面的下沉．试验分空接头、软接头和刚性连接及插入式方案４种情况．对每种试验情况都进行二维和三维有限元计算，并将实测值与计算值对比．空接头防渗墙内应力在试验情况下只有刚性连接的一半，软接头及插入式方案的可减缓墙内应力．三维计算防渗墙应力与实测值符合，二维计算值偏大．
In this paper, large-scale model test of impervious wall joint is introduced. The stress in the concrete cutoff wall, the relative displacement between the corridor and the cut-off wall and the sinking of the fill surface are measured. Test points empty joints, soft joints and rigid connections and plug-in programs 4 kinds of situations. Two-dimensional and three-dimensional finite element calculations were performed for each test case, and the measured and calculated values were compared. Impermeable wall empty joints in the test case only rigid connection half the soft joints and plug-in programs can slow down the wall stress. Three-dimensional calculation of impervious wall stress and measured values in line with the two-dimensional calculated value is too large.
