滑坡床形态的定量描述

Quantitative Description of Shape of slide Bed

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。

Take landslides in Sujiaping, Zhenxiong and ximent in Yunnan province as examples, the shape of slide bed is described with trend surface analysis of low order. Formulas for calculating spatial occurrence and azimuth of principal axis section of slide bed are derived by analytic geometry method to provide data for the calculation of stability of principal axis section of the slide and for designing the axial azimuth of slide-resistant structure.
