摘要: 为了研究固化疏浚泥的渗透特性,对不同养护条件、固化剂掺入量和龄期的固化疏浚泥进行了室内变水头渗透试验研究。结果表明:在养护条件一定时,固化疏浚泥的渗透系数随着固化剂掺入量和龄期的增大而减小;可用于工程防渗的最佳固化剂掺入量为6%~8%,而在固化剂中添加10%粉煤灰后的最佳固化剂掺入量为5%。试验结果对工程设计和施工具有重要的工程应用参考价值。

Abstract: In order to study the permeability characteristics of solidified dredged mud, we carry out indoor experiment with variable water head. During the experiment, the effects of curing condition, blending ratio of curing agent and curing age are taken into consideration. The results show that under given curing condition, permeability coefficient decreases with the increase of blending ratio of curing agent and curing age. Furthermore, the range of appropriate blending ratio of curing agent for permeability prevention in actual projects varies from 6% to 8%, and appropriate blending ratio of curing agent with 10% of fly ash is 5%. The test results offer reference for engineering design and construction in similar projects.

Key words: solidified dredged mud, permeability test, blending ratio of curing agent, permeability coefficient, permeability characteristics
