To control foundation seepage and exit gradient, a plastic concrete cut-off wall, a grout curtain, and a set of downstream pressure relief Wells are incorporated in the design.

为了控制基础渗流和出逸坡降，设计采用了塑性混凝土防渗墙、帷幕灌浆以及在下游增设一套减压井相结合的方案。

Thus the difficulties of discontinuous velocity gradient and the stress singularity at the exit point are avoided, and the expense of computation is reduced.

这样回避了速度梯度间断的困难，缓和了出口处应力奇性引起的矛盾，同时又减少了计算量。

Results showed that the temperature, temperature gradient and thermal stress at the exit surfaces of the CWS ceramic nozzle were higher than that of other part of the nozzle.

结果表明：在陶瓷水煤浆喷嘴的出口端面存在较大的温度、 温度梯度和热应力。
