摘要
水江坪河河间地块地质结构简单，碳酸盐岩分布广，岩溶发育，河间地块内存在六个相互独立的岩溶地下水系统，各系统进口高程均在６４０米以上。地质分析及物探证实，在近水河岸处，分布一高程为７００米左右，宽约８００米的地下水分水岭，因此水库蓄水后不可能通过岩溶地下水系统向库外产生岩溶渗漏。
The geologic structure in the inter flow area located in the right bank of Jiangpinghe reservior on the Loushui River is very simple. But,in this interflow area there exists widely carbonate rock strata and karst erosion,and six independent karst groundwater systems with intake elevation of all above 640 m. Geologic analysis and geophysical prospecting confirm that Inside the bank of Loushui River there is an underground divide with elevation of 700 m and width of 800 m.Thus,when the reservoir impounds water,the occurrence of reservoir leakage through the karst groundwater systems in interflow area is impossible.
