引言虽然标准渗水试验已成为评价水砂充填料脱水特性的一种通用方法,但是大家公认,由于下列缘故试验结果要做大量整理工作: (1)改变试样制备方法将改变试样材料取用量,从而可能对试验结果有很大影响。特别是试样上部的薄层细泥,可能影响试样中的进水量。帮壁的边缘效应也可能影响试验结
INTRODUCTION Although the standard seepage test has become a common method for evaluating the dewatering characteristics of water sand packings, it is generally acknowledged that a large amount of testing should be done due to the following reasons: (1) Changing the sample preparation method will change the amount of sample material taken , Which may have a significant impact on the test results. In particular, a thin layer of fine mud in the upper part of the specimen may affect the amount of water infused into the specimen. The edge effect of the wall can also affect the test results
