运用坍塌平衡法计算，应考虑土洞平面形状的影响，同时土层的内聚力c不能被忽略；

The plane shape of soil cave should be taken into account in using ' collapse balance method ' , in the meantime , the cohesion c should not be neglected .

作为一种有效的探查技术，等偏移横波（SH）反射法具有探测迅速，易于探测土洞、地下岩溶裂隙带的特点。

As an effective investigation technique , common-offset SH reflection method can be carried out fast in the field and easy to detect caves and underground karst fracture zones .

浅部岩溶发育，覆盖层厚度一般小于20m，土洞较多，基岩面起伏大，第四系岩性结构复杂，地下水埋藏浅。

Karst is developed in the shallow part and the thickness of covered layer is less than 20 meters . At the same time , earth cave is very often seen , bedrock is fluctuate , lithological texture of Quaternary is complex and the water level of groundwater is .
