摘要
提出圆弧滑动法中一种新的搜索方法———三向搜索法。圆弧滑动法可以利用其共性而不局限于一些经验假设 ,在坡顶线及其下部各道坡线间都存在一个安全系数最小的圆弧 ,针对这些圆弧的寻找 ,给出了具体办法 ,并给出几个计算实例。
A new search method of arc slipping method, which is called three orientation search method in the article, is given. It is pointed out that there always exists an arc with the least safe coefficient between one slope top line and each of those lines which is below the slope top line; In order to find all these arcs, a concrete method is given, and finally some examples are described.
