| 摘要: |
| 井阻和涂抹作用是排水板地基中普遍存在的现象，但在目前的排水板地基设计和分析中，却很少考虑。本文具体分析了井阻和涂抹作用对地基固结的影响，提出了考虑井阻和涂抹作用的分析和设计曲线，并建议井阻因子Ｇ＝ ０．１５ 和涂抹因子Ｊ＝ ０．１ 可作为考虑井阻和涂抹作用与否的标准，从而为非理想井的分析和设计提供了一条简捷、合理的方法。 |

| Abstract: |
| The well resistance and smear effect are generally existing in soils treated with prefabricated drains , but they are always ignored in design. In this paper, the well resistance and smear effect are analyzed and some transformation curves are given, it is suggested that G =0.15 and J =0.3 can be the criteria whether to consider the well resistance and smear effect or not, giving a simple and rational method in analyses and design for the non ideal well. |
