摘要
文章通过详细的野外地质调查,基本查清了贵安直管区范围典型岩溶管道的分布特征。其中溶洞主要分布在地形起伏相对较大的地区,对洞口标高系统统计结果显示,主要集中分布在1225~1325 m、1425~1475 m等多个高程段;地下河进出口露头集中分布在1175~1200 m、1250~1275 m高程段,主要受地形控制;岩溶漏斗、落水洞的分布一定程度上受地层分布的控制,岩溶塌陷则显示与区域断层的分布密切相关。综合分析认为区内岩溶管道的分布明显受地形地貌、地层分布、区域断裂构造分布的控制,整体显示阶段性、多期次发育特征。在此基础上,初步讨论了岩溶管道网对直管区地下空间利用的制约,根据实际情况提出中–浅层地下空间(0~−30 m)分区规划、整体统筹的建议。
Through detailed field geological survey, the distribution characteristics of typical karst pipelines in Gui’an direct territory are basically identified. The karst caves are mainly distributed in areas with relatively large relief, and the elevation system statistics show that they are mainly distributed in several elevation segments such as 1225~1325 m and 1425~1475 m. The outcrops at the inlet and outlet of the underground river are mainly distributed in the elevations of 1175~1200 m and 1250~1275 m, which are mainly controlled by topography. The distribution of karst funnels and sinkholes is controlled by stratigraphic distribution to some extent, and the karst collapse is closely related to the distribution of regional faults. Comprehensive analysis shows that the distribution of karst pipeline network in this area is obviously controlled by topography, stratigraphic distribution and regional fault structure distribution, and shows the characteristics of phased and multi-stage development. On this basis, the restriction of karst pipeline network on the utilization of underground space in the Gui’an direct territory is discussed, and the suggestions according to the actual situation of zoning planning and overall planning of middle-shallow underground space (0~−30 m) are put forward.
