The cavity around underground waterside structure has been recognized as primary factor of cave-in in the road, seepage-failure of the river levee, etc. There are numbers of experimental studies on the mechanism of hollowing out. However, no research has yet been carried out to clarify the causal relationship with numerical description. In this paper, we developed a 2-phase groundwater flow model by incorporating Manning's law for intracavernous flow. Its applicability is shown by numerical experiments and actual scale calculations. These results show that the proposed model is effective for expressing time-dependent behavior of air and water during the cavity-detecting test.
