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.
