摘要
季节性天然降水在补给区内聚集 ,沿着渗透通道逐渐形成一定规模的土洞 ,它受特殊的地形地貌单元、地层结构补给与排泄条件制约 。
The seasonal precipitation gathers in the recharge areas, goes along permeable passage and gradually forms the karstic earth cave of a certain scope. It has condition each other with the special landform unit,statigraphic struction, recharge and drainage. Its pan erosion effect has a potential unsafety influence on nearby surface structures.
