用平衡加压法在三联中低压固结仪上进行控制竖向变形的膨胀力试验,并通过改变试样初始含水量、干密度,研究了膨胀力随初始含水量、干密度的变化规律.试验结果表明,膨胀应变略微增加,膨胀力大幅降低;膨胀力与干密度、初始含水量及膨胀应变成指数关系.基于这些试验成果,采用多元回归分析,求得膨胀力的拟合式.

Via a series of swelling tests conducted on consolidation apparatus, the vertical swelling pressure with the deformation of remolded expansive soils was studied. According to the tests results, it is concluded that: the vertical swelling pressure is remarkably decreased with the increase of small swelling strain; the swelling pressure and dry density, initial moisture content and swelling strain present exponential relations. With the help of multiva-riate regression analysis, fitted regression equation of swelling force is found.
