摘要

Knothe时间函数可预测地表下沉

但其不能反映地表下沉速度和加速度的变化规律。针对Knothe时间函数描述的不足

提出了改进的地表下沉的时间函数——基于Logistic增长模型的时间函数。该时间函数可合理描述地表下沉发展变化的全过程

能反映实际地表点下沉的速度和加速度的变化规律

经实测检验

证明了该时间函数的实用性和有效性。

Abstract

Knothe time function is used to forecast surface subsidence

but the Knothe time function cannot simulate the subsidence rate and acceleration. According to the limitation of Knothe time function

the improved time function of surface subsidence

time function of surface subsidence based on Logistic growth model

is presented. Logistic time function can describe the whole process of surface subsidence and simulate the subsidence rate and acceleration according to the measured data of mine. The results indicate that the method is effective and applicable.
