桂林市柘木岩溶塌陷成因及其分布的基本特征

Primary Characteristics and Occurrence of Karst Collapse

拓木岩溶塌陷分布在漓江Ⅰ级阶地与河漫滩的结合部位，受NW向和NE向断裂控制，岩溶塌陷成因以振动致塌和冲爆致塌为主，直接的诱发原因是炸礁爆破的振动作用。

Karst collapse is mainly distributed at the joint belt of the first-step terrace and the flood land of Lijiang River in Zhemu village. Controlled by the NW and NE faults, the karst collapse is basically caused by vibration collapse and explosion-impact collapse,which are directly induced by blasting the reef.
