摘要
岩体内部开采沉陷计算的关键是层面的滑移位置及滑移函数。本文根据多层复合板理论，推出了三维条件下，开采沉陷中层面滑移函数和层面滑移位置判断式，获得了平面上最大滑移方向计算式。结合相似材料模型观测结果，验证了所给公式的适用性。
The position for stratification plane gliding and its function play a key role in mining subsidence calculation. Based on the theory of composite plate, this paper derived a 3 D function of stratification plane gliding and a 3 D formula for the position of stratification plane gliding in mining subsidence, and obtained a formula for maximum gliding direction on the gliding plane. The applicability of the formulae is proved through the observation data from a model made of materials similar to those in field.
