Based on the acoustic wave sounding of the dam foundation of a water control project, the continuous ratio of J1~J4 inter layer shear zone is infered by analyzing the acoustic velocity anomaly.
以某水利枢纽工程坝基声波探测为例 ，通过声速异常分析 ，对J1～J4层间剪切带连续率进行了推定 ，其部分成果经开挖验证具有一定的可靠性。
In the upper layer, there are the blocking speed-down zone inter-belt, the whirling speed-down zone behind the belt, the conflux accelerating zone just behind the top of shelterbelt.
在林带上部，有林带间的阻滞减速区和林带后的涡旋减速区，在林带顶后部有集流加速区。
