拔贡水电站改扩建工程地形属岩溶峰丛-洼地地貌，地质条件复杂，岩溶发育。拔贡水电站旧坝评为病坝，厂坝基及坝肩渗漏严重。针对拔贡水电站库坝区岩溶水文地质特点，进行岩溶水文地质勘察工作，通过地球化学和示踪试验对该区地下水及岩溶水系统(水系)分区，确定库坝区岩溶水渗漏通道及岩溶多层性。为工程处理决策提供依据，对类似岩溶地质条件下的坝基防渗技术具有重要参考价值。
拔貢水電站改擴建工程地形屬巖溶峰叢-窪地地貌，地質條件複雜，巖溶髮育。拔貢水電站舊壩評為病壩，廠壩基及壩肩滲漏嚴重。針對拔貢水電站庫壩區巖溶水文地質特點，進行巖溶水文地質勘察工作，通過地毬化學和示蹤試驗對該區地下水及巖溶水繫統(水繫)分區，確定庫壩區巖溶水滲漏通道及巖溶多層性。為工程處理決策提供依據，對類似巖溶地質條件下的壩基防滲技術具有重要參攷價值。

The extension project of Bagong hydropowe r project has complex geological conditions, which belongs to karst peak cluster-depression landform and is developed with karst caves. The old dam of Bagong hydropower station is evaluated as a damaged dam because serious leakage problems existed at the powerhouse dam foundation and abutment. The karst water leakage passages and the karst layers are determined base on the survey on the karst hydrogeological characteristics of dam area and the geochemical and tracer tests on the underground water and the karst water system (water system), which provides a basis for engineering decision-making and can be well referenced by similar projects.
