| 摘 要： | 本文讨论了淤泥质饱和土渗透系数的实验方法,通过对比实验确定了误差范围,总结了实验的主要误差来源。依据浙江乐清北港区吹填土样、上海闵行河道土样的渗透实验结果以及国内外学者的渗透实验资料,提出了一个涵盖高含水率情况的淤泥质饱和土的渗透系数经验公式。通过与其他经验公式对比,本文提出的渗透系数经验公式有着合理的准确度和较广的使用范围,具有工程实用价值。

| Abstract: | A method for permeability test of saturated muddy clays was discussed in details. Different contrast experiments were carried out to find out the experimental error magnitudes resulting from different error sources. Based on the permeability test data of soil samples taken from the reclamation site of Yueqing North Port, the Minhang River of Shanghai and the data from other scholars, an empirical formula was proposed for predicting the permeability coefficient of saturated clays with the void ratio varying from low to high. Compared with other empirical formulas, this formula has a reasonable accuracy and broader applicability which is acceptable in engineering practice. |
