摘　　要：应用一维回归分析预测新滩滑坡变形的发展趋势,求得各阶段的累积位移一时间函数,并进一步求得变形加速度和变形速度随时间变化的函数关系。通过具体分析,认为变形加速度可作为蠕变滑坡的一个临滑预警指标,并将新滩滑坡临滑预警指标定为7.5 mm/月~2。Authors analyse and predict the development trend of Xintan landslide deformation by using one dimensional regression analysis method,and calculate cumulative displacement-time function in each stage of the creep deformation,further to get the function of deformation acceleration and velcocity s changing with time.In this paper,through the concrete analysis authors think the deformation acceleration as a eraly warning indicator of creep landslide,and predict the sliding warning index for 7.5.mm/yue^2.
