| 摘 要： | 丹霞地貌是地貌学研究的热点问题之一,但是,目前对岩性与丹霞地貌岩穴发育关系的理论研究仍处于定性阶段,缺乏具体实验支持.本文对丹霞山锦石岩进行实地采样,然后对所采集的砂岩、砾岩和泥岩样品进行单轴抗压强度实验和岩石偏光显微镜鉴定,并利用所得实验数据结果对丹霞山锦石岩大型水平岩穴的岩性差异与岩穴发育的关系进行了定量分析.结果表明,在上部岩石的压力作用和外力的长期侵蚀下,砂岩和泥岩由于岩性相对软弱,易遭受侵蚀而剥落.而砾岩的抗压能力、抗风化能力相对较强而得以保留.

| Abstract: | The study of Danxia landform is one of the hot topic in geomorphology.But for the present,theoretical study of relations between lithology and caves development of Danxia landform are still in qualitative stage,lacking of experimental support.Through field sampling in Jinshiyan of Danxiashan,this paper did uniaxial anti-pressure strength test and polarizing microscope identification for the collected sandstones,conglomerates and mudstones,and quantitatively analyzed the internal relations of lithological di... |
