| 摘 要： | 公路路基下伏空洞为天然和人工产生，严重危害公路路基的稳定．笔者通过对空洞的地质背景研究，分析了空洞成因、类型及演化规律；将空洞上覆的岩层划分为冒落带、裂隙带、弯曲带等３个带，阐明了覆岩的岩性和构造特征，总结了影响冒落的因素、地表的破坏形式和地表变形特征，建立起了地质模式和工程地质模式．

| Abstract: | he holes under the foundation of freeway are formed by natrual and humanactiuies. Because of the existence of these holes, the stability of the foundation of freeway aredemaged deeply. Acccording to the study on the geologic setting of the holes, the formation,types and evolution of the holes are analysized and three zones (the collapse zone, fracturezone and bend zone have been distinguished. In this paper the lithologic and structuralcharacteristics about the overlying rocks of the holes are interpreted and the factors ofinfluencing collapse, destroying formation and transmutative formation on the ground aresummarized. The geologic model and geologic engeenering model are finally established. |
