针对国外EPC合同项目前期勘测工作极少的特殊情况, 充分利用小口径钻孔、高清孔内录相、现场试验, 结合开挖揭露的河床周缘地质情况分析, 及时、准确、快速查明河床坝段的地层岩性、地质构造、岩体结构、岩石力学参数, 为设计复核坝体稳定性提供定量的地质评估依据.

Focusing on the special condition of Foreign Hydropower Station project with few preliminary investigations , the authors make full use of small-diameter drilling ,high-definition photographing inside hole and field test to investigate geological conditions .Based on this ,combined with the geological analysis of the excavation-composing riverbed 's periph-ery,formation lithology,geological structure,rock mass structure and rock mechanical parameters in the riverbed section can be identified timely ,accurately and rapidly ,providing a reliable geological basis for designing and reviewing the sta-bility of the dam.
