摘要
通过对土洞发育及形成条件的初步探讨，认为红粘土土洞是由于红粘土的胀缩性和地下水、溶隙等潜蚀作用造成的．模型断面上电测深曲线形态与实际工作结果有较好的统一，对评价地基的稳定性，预助水土流失等均有较好的指导意义．
In this paper, a preliminary investigation thr the red clay cave development and its condition was carried out. The result showed that the expand and contract character of the red clay, the erosion and dissolution of tLhe groundwater caused the formation of the red clay cave. The results from resistivity logging curves on mould profile and that from the real prospecting were concord satisfactorily,It has a significancc to the evaluation of the fotundation stability, prevention of the soil erosion etc.
