An experimental research on the mechanical indexes, swelling-shrinkage properties and pore size distributions of intact Guangxi laterite at different stages of dehydration, has been carried out systematically.
结果表明:广西原状红粘土为裂隙发育的硬塑性粘土,不同脱湿阶段的力学指标与胀缩性能在较高含水量范围内受基质吸力控制,在较低的含水量范围内主要受控于裂隙性;转折点处含水量与重型击实(干法备样)最优含水量相接近;原状红粘土的孔隙主要以孔径从0。
6) swelling-shrinkage behavior
胀缩性状
1.
Compacting properties,swelling-shrinkage behavior and mechanical behavior of compacted sample for weak expansive soils in Xiang-Jing Expressway of Hubei Province are investigated.
针对湖北襄—荆高速公路膨胀土,在室内开展了弱膨胀土的压实特性、胀缩性状、力学特性试验研究,发现压实膨胀土的工程性状受含水率与压实度的影响,胀缩特性是膨胀土的固有特性,其大小取决于起始湿度和密度;击实膨胀土的最佳含水量和最大干密度随击实功变化而变化,压实功愈大,土的最大干密度也愈大,而对应的最佳含水量愈小;膨胀土的CBR值随其含水率的变化规律类似于击实曲线,但CBR峰值含水率大于最佳含水率,为深入认识膨胀土的工程特性提供了帮助。
