本文以云南省苏家坪、镇雄和西盟滑坡为例,用低次趋势面分析描述滑床形态,并据解析几何方法推求出滑床的空间产状和主轴断面方位的计算公式,以供滑坡主轴断面稳定性检算和布置抗滑构筑物轴线方位之需要。
Taking the cases of Sujiaping, Zhenxiong and Ximeng landslides in Yunnan Province as an example, this paper describes the shape of the sliding bed using the analysis of the low order trend surface and deduces the formulas for calculating the space shape and the cross section orientation of the sliding bed according to the analytical geometry method It is used for checking the stability of landslide spindle and arranging the anti-slip structure axis orientation.
