According to a typical karst depression,on the basis of its development characteristics,the FLAC3D numerical method was used to simulate the forming and evolution processes of the karst depression.

以典型喀斯特洼地——贵州省平塘县高务洼地为地质原型,在查清其发育特征的基础上,用FLAC3D数值模拟方法,对其发展演化过程进行了三维动态仿真,从而从地质力学的角度得出岩溶洼地形成的动力演化机制。

This paper discusses the character of many big Karstic features conformation such as Karst depression,trough and gigantic combination trough and underground Karst cave as well as their forming mechanism and factors controlling them.

圆梁山隧道毛坝向斜段核部及两翼的可溶岩地层中发育分布有大量的典型岩溶现象 ,本文详尽讨论了岩溶洼地、槽谷、巨型组合槽谷和地下溶洞等大型岩溶形态的基本特征、形成机制、受控因素 ,并进一步认识到其发育分布主要受控于岩性和构造因
