温度作用下黄土含水量分布的实验研究

The water content distribution in loess soil on temperature gradient

取初始含水量分布均匀的黄土土样,测试了不同温度梯度作用下的稳态含水量分布,测试结果表明:温度对土样中含水量分布的影响非常显著,温度梯度作用下的稳态含水量梯度方向与温度梯度相反,温度梯度越大,含水量梯度越大.温度对土样含水量分布的影响也与土样的密度有关,密实度越小,温度梯度作用下的稳态含水量梯度越大.

Taking loess soil sample with uniform original water content, the water content distribution of the soil is tested in various thermal gradients. The test results show that the water content distribution changes obviously with the thermal gradient on the soil . The water content gradient orientation is reverse to the temperature gradient. The greater is the temperature gradient and the lower is the soil density, the greater the water content gradient is.
