山口大坝廊道排水孔析出物分析

Analysis of Drainage Holes in the Corridor of the Mountain Pass Dam

大坝廊道排水析出物的产生是一个普遍现象,正确认识析出物的成因,是评价坝基渗透变形、坝基灌浆帷幕工作状态的基础。针对山口大坝廊道析出物的特征、类型和成分进行了分析,探讨渗出物质的主要可能来源和成因机制。

it is a common phenomenon that the drainage of the drainage of the dam corridor is a common phenomenon,which is the basis for the evaluation of the working condition of the dam foundation seepage deformation and the foundation grouting curtain. The characteristics,types and composition of the precipitates in the corridor of the mountain pass dam are studied in this paper. The main possible sources and the formation mechanisms of the material are discussed.
