【摘要】 通过对土工布垂直渗透试验和反滤试验,了解不同规格的土工布在垂向水流作用下的渗透性,并判断土工布作为粉煤灰滤层时是否会产生淤堵。为进一步优化坝型,保证灰场的安全、经济运行、节约投资,利用有限元方法计算灰坝二维渗流场,并对结果进行分析,确定最优灰坝的筑坝方案。更多还原

【Abstract】 Finding out the penetrability rule of different kind of geotextiles via vertical seepage and filtration examinations, authors estimate whether jam which is not allowed would be brought by the using of geotextile as the filter bed of ash dam . In order to optimize the dam model, and insure the safe and economic operation of the ash dam, the 2D seepage area which is used to confirm the scheme of the dam is calculated by the using of finite element method.更多还原
