地层沉陷中的突变现象及其研究进展

Catastrophe Phenomena and Research Progress of Strata Subsidence

通过大量的现场勘测、相似材料模拟实验和数值模拟，发现了地层沉陷中的突变现象，系统地研究了地层沉陷过程中的岩体突变破坏机理，展望了地层沉陷突变现象的发生和机理研究的理论价值和工程意义。

The catastrophe phenomena of strata subsidence is discovered through a lot of field survey, similar material simulation and numerical simulation. The mechanism of rock mass catastrophe failure in the process of strata subsidence is systematically studied in this paper. The theoretical and engineering value of them is prospected.
