贵州盘县平关镇仙人洞测量及成因探讨

实地测量了贵州盘县平关镇仙人洞双层水平洞穴系统,绘制了洞穴三相图,洞穴Ⅰ和洞穴Ⅱ长度为123m和85m。依据测量结果及区域地貌对该洞穴系统的成因及演化过程进行了综合分析,认为在岩层裂隙和节理不发育的情况下,岩溶水相对孤立,不存在统一的地下水面,岩层走向控制岩溶洞穴走向的发育。该水平洞穴系统不是早期小河的通道,其排泄区位于北部的沈家河,区域内早期未发生河流袭夺现象。依据洞穴通道特征认为该洞穴系统发育经历了深潜时期、渗流时期、干燥时期。

Measurement of and Investigation on the Genesis of the Xianren Cave in Pingguan Town Panxian,Guizhou Province,China

The Xianren Cave was located in Pingguan Town,Panxian,Guizhou Province,and the long section,cross section and plan section were mapped. CaveⅠ and CaveⅡ were measured to be 123 m and 85 m in length,respectively. While the genesis and evolution of the Xianren Cave system were analyzed on the basis of measurements and geomorphic features of this area. It is shown that karst groundwater is isolated,there is not a unified water level and the strike of the cave was controlled by the strike of rock if fissures and joints of the rock were not developed well enough. The Xianren Cave system was not the channel of the river which existed long time ago,and the Shenjiahe River located in the north of the Xianren Cave is the water discharge area from the Xianren Cave. No rivercapture has been found in this area never before. The development of the Xianren Cave experienced the deep submergence period,seepage period and dry period.
