应用相似材料模拟实验研究了盐腔成腔过程中上覆岩层移动、变形和破坏规律,上覆岩层损伤演化过程及规律,上覆岩层的层面效应及分层特性,上覆岩层破碎岩体尺寸特性等内容。通过这些研究,获得了上覆岩层在盐腔形成过程中的损伤演化方程、上覆岩层因岩层性质不同而产生的分层特性、上覆岩层移动变形过程中表现出来的层面效应以及岩层破碎岩体尺寸与岩层力学性质的关系。为进一步弄清开采沉陷的微观机理和建立新的预测模型打下了基础。
The similar materials simulation experiments were carried out to study the movement, deformation and failure of overlying strata, the evolution process and rule of overlying strata damage, the stratification and stratification characteristics of overlying strata, the size of overlying strata Features and so on. Through these researches, the damage evolution equation of overlying strata in salt cavity formation, the stratification characteristics of overlying strata due to the different rock properties, the stratification effect of overlying strata during the deformation process and the fractured rock Body size and mechanical properties of the rock. Which laid the foundation for further understanding the micro-mechanism of mining subsidence and establishing a new prediction model.
