Elastic statics mainly relates to the connection between force and transmogrification, elastic body's invalidation, the guide line of design in invalidation.

弹性静学主要涉变之间的物性关系，以弹性体的失效、失效有关的设计准则。

However, the caving maybe happen because of too large transmogrification and rheologic fracture to high crustal stres.

统一流变断裂准则，成了诱导条件下节理岩体持续大规模自然崩落判据。
