摘要：

A case of the formation of underground cavities to depths of some metres in loose sandy Quaternary sediments is described and the factors controlling their appearance and evolution are discussed. Special attention is given to the role of underground erosion, through the circulation of water, and to the importance of grain-size analysis of the sandy soil, as well as to the presence of slightly differentiated soil material (silty sand or clayey sand) distinguished in thin intercalations. This material, with only slightly increased cohesion, has the function of a rooting material in the mechanism of cavity formation.
