岩土是一种极其复杂的材料,无论何种数学模型都难以全面准确地描述它的工程特性。由于地质条件差异,造成采空区环境稳定性影响因素复杂多变,目前国内、国际上对于采空区各方面的相关研究均处于探索阶段,无十分成熟的采空区研究、评价规范及模式。作者在研究贵阳某采空区勘察成果的基础上,直接从实际现象入手,将传统的动水位观测应用于采空区顶板覆岩变形分析,并与其它理论、手段取得的成果进行对比分析,对采空区勘察尤其顶板覆岩变形的勘察研究提出了很有参考价值的方法。
Geomagnetism is an extremely complex material, and it is difficult to describe its engineering characteristics comprehensively and accurately regardless of the mathematical model. Due to the difference of geological conditions, the factors affecting the environmental stability of mined-out area are complex and changeable. At present, the relevant research on mined-out area in both domestic and international are in the exploration stage, and there is no mature research, evaluation norms and modes . Based on the research results of a goaf in Guiyang, the author starts from the actual phenomenon directly and applies the traditional dynamic water level observation to the deformation analysis of the overlying strata in the roof of the goaf, and makes a comparative analysis with the results obtained by other theories and methods. The study of the mined-out area, especially the deformation of overlying strata in the roof, puts forward some valuable methods.
