摘要
渗透系数是直接反映土体渗透性的参数,是土工计算分析中的关键参数,其值的准确求取有重要的工程实际意义。IFCO BAT系统是一套能快速、准确获取地基孔隙水压力和原位渗透系数的先进测试系统。据此,总结介绍IFCO BAT系统测试地基孔隙水压力和原位渗透系数的理论,并介绍其在吹填土大型模型槽试验中的应用。实践证明:IFCO BAT系统的渗流分析理论及其渗透系数求取是正确的、合理的,并有很高的工程实用价值。
Permeability is a key parameter in calculating and analyzing of geotechnical engineering; and its accuracy is very important. IFCO BAT system is a set of in-situ test system, which can gain the pore water pressure of ground and in-situ permeability of soil quickly and accurately. The theories for in-situ test of pore water pressure and permeability by IFCO BAT system were generally introduced. The applications to model test of dredger clay show that the theories are correct and the in-situ test results are accurate; and IFCO BAT system can be used in geotechnical engineering.
