黔中水利枢纽平寨水库大坝左岸岩溶十分发育，受岩性和构造影响共发育五套岩溶系统。针对平寨水库左岸防渗帷幕地段，基于施工现场左岸帷幕灌浆平硐揭露溶洞发育信息，分析岩溶溶蚀特征，归纳岩溶发育规律。研究得出岩溶溶蚀受地质构造和地层岩性影响在垂直方向上岩溶溶蚀由上往下逐渐增强，在水平方向上溶蚀离河岸由远及近逐渐增强，局部区域受地层岩性和构造控制集中发育的岩溶发育规律。
黔中水利樞紐平寨水庫大壩左岸巖溶十分髮育，受巖性和構造影響共髮育五套巖溶繫統。針對平寨水庫左岸防滲帷幕地段，基于施工現場左岸帷幕灌漿平硐揭露溶洞髮育信息，分析巖溶溶蝕特徵，歸納巖溶髮育規律。研究得齣巖溶溶蝕受地質構造和地層巖性影響在垂直方嚮上巖溶溶蝕由上往下逐漸增彊，在水平方嚮上溶蝕離河岸由遠及近逐漸增彊，跼部區域受地層巖性和構造控製集中髮育的巖溶髮育規律。

Affected by the lithology and structure ,the karst on the left bank of Pingzhai Reservoir have developed five layers of karst system .Based on the information investigation for the grouting tunnels with anti-seepage curtain ,the quan-titative analyses were performed about the karst corrosion characteristics and karst developing regularity .The conclusion is that the karst corrosion would gradually strengthen from up to down in the vertical direction ,and gradually strengthen from off-river to near-river direction .Simultaneously there exist some centralized corrosion regions which are controlled by the formation lithology and geological structure .
