However, the displacement and deformation of surface ground by underground mining have destroyed initial equilibrium between the building and the ground.
但是由于地下开采引起地表产生的移动和变形，破坏了建筑物与地基之间的初始平衡状态。
This is due to the coupling of inhomogeneous deformation and the brittle equilibrium phase on the boundary.
这是由于变形不均匀和晶界上析出的平衡脆性相耦合作用的结果。
The results show that, increasing cooling rate, pre-deformation and grain refinement are useful for spreading of the non-equilibrium microstructure around the primary grains.
结果表明：增加冷却速率、预变形处理和晶粒细化有利于初始凝固组织中存在的非平衡组织的分散细化。
