中文摘要：
用三向胀缩仪对南阳陶岔重塑膨胀土做了12个三向膨胀力试验,9个湿胀干缩试验和9个控制变形的膨胀力试验.试验结果表明,三向膨胀力不等,水平膨胀力小于竖向膨胀力;湿胀干缩使重塑膨胀土的膨胀力降低,第一次干湿循环后膨胀力减小最多;微小的位移可以使膨胀力大大降低,膨胀力与位移呈对数关系;给出了膨胀力与初始含水率和干密度的关系式.
英文摘要：
A series of tests were conducted for the unsaturated expansive soil using three-dimensional swell-shrinking device. The three-dimensional swell-shrinking characteristics of remolded expansive soils was studied. According to the test results, three-dimensional swelling pressures are unequal. The lateral swelling pressure is smaller than vertical swelling pressure. The swelling pressure of remolded expansive soil is decreasing with wet-dry cycles. And a small strain could bring obvious decreasing of swelling pressure. The logarithmic relation between lateral pressure and strain is proposed. A formula of vertical swelling pressure with initial water content and dry density is given.
