摘要
以西藏某水电站坝址区内所有平硐的回弹裂隙风化特征的实测资料为依据,针对回弹裂隙的风化特征进行了统计分析,对电站的建设有重要的理论依据和实践意义。研究内容包括基于整个坝址区域内的所有平硐的回弹裂隙风化等级,建立了裂隙风化建议值指标;按照坝址区整体、不同高程、不同卸荷带、不同坝线的思路,用形象的图片形式表现了坝址区不同高程所有平硐的裂隙风化特征分布的情况,目的是对电站裂隙风化特征做相应的评价,得出其分布特征。
Based on field investigation of some water power station's all fractures' weathering featuresin Xizang,purposed on mid-low angle fractures weathering properties,quantitative analysis is carried out.It has important theoretical and practical significance to the construction of the power station.These all are studied,pointed at all the fractures weathering descriptions weathering suggestion index is established; According to whole studying area different elevations; different unloading zone and different dam lines,using abstract pictures,all different elevations' mid-low angle weathering fractures' distributions are shown.Finally,those finished are quantitative analysis and evaluation pointed at mid-low angle fractures.It is obtained that mid-low angle fractures have some zonal distribution features in vertical elevation direction and cave spreading direction.
