在分析各种反滤层设计方法的基础上,根据康德拉契夫的试验资料,提出了反滤层设计的新原则。本原则考虑了逸出渗透坡降的不同而对滤层构造的要求亦随之改变的情况,以及铺设反滤层后会反转提高被保护土壤的抗渗强度这一因素,为更广泛的范围内选择反滤层材料提供了理论依据。 On the basis of analyzing various design methods of anti-filter layer, a new principle of anti-filter layer design is put forward based on the test data of Kantrachev. This principle takes account of the different requirements for the structure of the filter layer due to the differences in the permeate gradient and the factors that reverse the anti-seepage strength of the protected soil when the filter layer is laid, Select the scope of the filter material provides a theoretical basis.
