| 摘 要： | 本文对宁夏膨胀土进行了膨胀变形试验，结果表明，膨胀土的膨胀变形受含水量、干密度和压力的影响。膨胀量是含水量的线性函数，膨胀量的对数与压力的对数呈直线相关。这一结果应用于工程实践中，简化了膨胀土地基的膨胀量的计算公式，得到了较好的结果。

| Abstract: | The expansive deformation of Ningxia expansive soils are investigated.The test results show that linear relationships exist between swell and water as well as the logarithm of swell and the logarithm of pressure.These relationships canbe used in geotechnical practice. |
| |
| Keywords: | expansive soil swelling deformation swell. |
