在讨论地质背景与洞穴发育关系的基础上,结合洞穴中冲、溶蚀形态特征、第四纪不同时期的沉积物剖面及沉积旋回分析、粒度分析、砾石统计等资料,系统分析了洞穴发育过程中的古水流方向。测年资料表明,多层洞穴不同时代的堆积物记录,反映了新构造运动和气候波动对洞穴发育的控制作用,为评价洞穴的发育规模、展布方向及对工程的影响,提供了可靠的科学依据。
Based on the discussion of the relationship between the geological background and the cave development, this paper systematically analyzes the relationship between the development of caves and the development of caves based on the characteristics of red and dissolution in caves, sediment profiles in different periods of Quaternary, sedimentary cycle analysis, grain size analysis and gravel statistics. The ancient water flow direction. The dating data show that the records of sediments from different ages of multi-layer caves reflect the controlling role of neotectonic movement and climate fluctuation on the development of caves. In order to evaluate the development scale, distribution direction and impact on caves, it provides a reliable Scientific basis.
