摘要
风化土料一般具有压实性好、力学强度高、稳定性好等优点,现已成为多数水电工程防渗体的首选料源。土料天然含水率试验资料用于评价土料筑坝的适宜性及施工的难易程度,是土料的主要技术质量指标之一。由于母岩岩性、结构、风化程度不均一,致使风化土料天然含水率试验值离散性大,分布范围宽,给土料的质量评价带来一定困难。介绍糯扎渡水电工程风化土料天然含水率的统计分析,从理论上证明了其呈正态分布。
Weathered soil generally has the advantages of compactibility, high mechanical strength, good stability etc., and now it has become the preferred material source in most Hydropower Engineering impervious body. Soil natural water content test data are used for the evaluation of the suitability of dam construction soil and the difficult degree of construction, It is one of the main technical indicators of the quality of soil material,, and iIts test data are used for the evaluation of damming the soil suitability of dam construction soil and the ease difficult degree of construction, is one of the main technical indicators of the quality of soil material, dDifferent rock types , structure and, weathering degree result in weathered soil natural water content test data of the great value of discrete distribution range, and bring some difficulties to the quality evaluation of soil material. In this paper, the Nuozhadu Hydropower Project the weathered soil natural water content test data of the Nuozhadu Hydropower Project were statistically analyzed, and theoretically proved that the data followed the normal distribution. The method of statistical analysis can be a reference for similar projects.
