At the same time, based on stable slope Angle on water and underwater measured in field, we adopted diagrammatical method to predict the area.

同时，也根据野外实测的水下和水上稳定坡角，采用图解法进行坍岸范围预测。

This study found that, as grain-size changed from coarse to fine, the underwater stable slope Angle changed from big to small on different loose accumulation slopes.

本文研究发现，不同松散堆积体水下稳定坡角具有随颗粒由粗变细，坡角由大到小的特征。

Using the formula proposed abutment locations to determine the consult position and the stable angle of slope.

然后利用桥基位置确定公式提出了桥基参考位置、岸坡稳定坡角和安全距离。
