摘　　要：岩盐水溶开采后,形成巨大空间的盐穴,可以利用盐穴存储石油、天然气。盐穴的收缩将引起盐穴容积减少,导致存储空间减少和地表下沉。地表移动变形监测是发现盐穴收缩变化的重要手段,由于目前国内没有专门的监测标准,本文提出采用国家标准GB 50026—2007作为测量规范。基于岩盐水溶开采与地下煤层开采引起地表移动规律基本相似,把盐穴收缩引起的地表下沉视作一个随机过程,把圆柱形盐穴容积收缩量转换为等效开采厚度和正方形开采区域,基于克诺特影响函数,建立了圆柱形盐穴收缩引起的地表下沉预计模型。When the halite is mined by water soluble,an enormous salt cavern is formed.It can be used to store petroleum and natural gas. The shrink of salt cavern causes volume reducing,storage space decreasing and surface subsidence. The monitoring of surface movement and deformation is an significant way to find out the shrinkage change of salt cavern.There is not special monitoring standard in China,national standard GB 50026—2007 should be adopted.Surface movement law of halite water soluble mining is mostly similar to underground coal mining,the salt cavern shrinkage is as a random process,volume shrinkage as equivalent mining thickness,cylinder salt cavern as equivalent cube.Based on Knothe influence function,the prediction model is established by cylinder salt cavern shrinkage.
