摘要
在文得根水利枢纽工程中,遇到了一层含砾粉土质砂,经过分析与研究确定该层为冰水沉积物,而且该层的分布是连续且稳定的。通过对其沉积特点和现场的分析与室内试验的数据得出一些工程特性,并通过对有无粘性土的论述与对比得出其允许水力比降的取值。
During the construction of the Wendegen hydro-junction project,silty sand with gravel is found.It＇s glaciofluvial deposit according to the result of some analysis and research.The stratum is continuous steadily.Some engineering characteristics had been made by the analysis of sedimentary characteristics as well as the site condition and the data of laboratory test.The permissible hydraulic gradient will be got through the discussion and comparison of whether soil is clayey soil.
