bedded formation

Numerical analysis of borehole stability in the bedded formation

层状岩石中井孔稳定性的数值分析

The rock formation of developing the stone forest occur as thick blocks and boast the joints striking EW, NS and other directions, and this set of thick-bedded rocks appear equally in thin and middle-thick stratiform from top to bottom.

形成石林的岩层为厚层块状，发育东西向节理，也有南北向和其它方向的节理，且这套厚层岩石上下均为薄&中厚层状岩石。
