前人对如何探明岩溶地下水流场类型、结构及性质做了大量的研究,特别在岩溶管道形态及组合与示踪曲线的对应关系上做了系统总结,但在岩溶管道和溶蚀裂隙的识别上尚需进一步研究。该文旨在研究岩溶管道和溶蚀裂隙在示踪实验和示踪曲线上的特征,设计了三组等截面积但不同截面形状的管道和裂隙示踪实验,通过分析对比实验得到示踪曲线特征,研究在一定条件下管道与裂隙中的水流形态与不同截面形状的关系,为岩溶调查时识别岩溶管道和溶蚀裂隙提供一定的依据。
The predecessors made a great deal of research on how to find out the type, structure and property of karst groundwater flow field. In particular, the author made a systematic summary of the karst pipe morphology and the corresponding relationship between the combination and the tracer curve. However, On the need for further study. The purpose of this paper is to study the characteristics of karst pipelines and dissolution cracks on the tracing and tracing curves. Three tracing experiments of pipelines and fractures with equal cross-sectional area but different cross-sectional shapes are designed. By analyzing and comparing the tracing curve characteristics , The relationship between water flow patterns and different cross-sectional shapes in pipe and fissures under certain conditions is studied, which provides a basis for identifying karst pipelines and dissolution fissures in the investigation of karst.
