| 中文摘要: |
| 分析了工程非适用土中的重金属含量及相关的物理参数,选取不同固化材量参量对非适用土中的淤泥土和粉砂土进行了界限含水量试验、固结试验和无侧限抗压强度试验。通过向淤泥土和粉砂土中添加固化材料,可显著改善这两种土的物理力学性能,固化淤泥土和固化粉砂土的无侧线抗压强度分别提高491%和598%,满足公路路基填土的要求。研究解决了非适用土的处置问题,为非适用土的资源化利用提供了新的途径,具有良好的经济效益和环境效益。 |

| The content of heavy metal and the physical parameters were researched.Boundary moisture content tests, consolidation tests and unconfined compression tests methods were introduced.It shows that the physical characters of modified soil are obviously improved.Unconfined compression strength of the two kind of modified soils along with 10 percentage of solidify materials have improved respectively 491% and 598%.The modified soils reached the requires of soils filled in highway subgrade.This paper solved the problems of treating unavailable soils and new approach is provided to reuse unavailable soil as a kind of resources.Application of unavailable soil has the fine economic benefits and environmental effect. |
