| 摘 要： | 为了查明金佛山各洞穴之间的地下水力联系，探讨岩溶地下水系统结构特征，于2016年12月进行了多元示踪试验。将罗丹明B作为示踪剂，从药池坝附近消水洞（S01）投入，验证消水洞与北坡水源（水房泉）（S02）之间存在水力联系。结果显示，示踪剂历时曲线为多峰型，推测地下过水通道可能由单管道型演变为多管道型通道；将荧光素钠投入金佛洞地下水流动处（S05）和将罗丹明B、荧光增白剂投入羊口洞地下水流动处（S03），利用高分辨率荧光光度计，于燕子洞（S04）在线监测。结果显示，金佛洞、羊口洞分别与燕子洞之间存在水力联系，且示踪剂历时曲线均为跳跃型，推测地下过水通道可能为发育有一定规模溶潭的多管道型。

| Abstract: | The purpose of this work was to clarify hydraulic linkage between every cave and structural characteristics of the karst groundwater system beneath Jinfoshan, Nanchuan district,Chongqing City. Multiple-element tracer tests were conducted in December 2016,in which the Rhodamine B was used as the tracer,and was injected into the Yaochiba sinkhole. A high-resolution online tracer technique was employed to determine the hydraulic connection between the drainage system of Yaochiba sinkhole and Shuifang spring. The duration curves of the tracer show a multi-peak shape, implying existence of a possible single-channel-type karst lake of a certain scale. Then tracers uranine and Rhodamine B were placed at groundwater flows of the Jinfo cave and Yangkou cave, respectively. Using a high-resolution fluorophotometer, online monitoring was conducted at the Yanzi cave. Results indicate that there is s hydroaulic relations between Jinfo cave ,Yanzi cave, and Yanzi cave, respectively, and the duration curves of the tracers all exhibit a jump shap.It is speculated that the underground water passage may be a multiple-channel-type with a certain scale of karst pools. |
