The cavitated bifurcation equation that describes cavity formation and growth in the interior of the sphere is obtained.
得到了描述球体内部的空穴生成和增长的空穴分岔方程。
Stability of solutions of the cavitated bifurcation equation is discussed in each region by using the minimal potential principle, and the catastrophic phenomenon of cavity formation is explained.
并利用最小势能原理讨论了空穴分岔方程的解在各个参数区域内的稳定性,解释了空穴生成的突变现象。
The study results show that the activity of underground water plays a key role in the whole process from the cavity formation to the occurrence of ground collapse.
