摘要
浅析了膨胀土石灰改良的机理和工程性质,介绍了石灰改良膨胀土的施工工艺和控制要点,在参考一般路基的工艺流程并结合石灰掺入工艺的基础上,总结了"三阶段、六区段、十流程"的施工工艺和施工过程中的控制要点,积累了石灰改良膨胀土路基施工经验。
With a shallow analysis on the principium of lime-treated expansive soils.and the engineering properties, it introduces the construction technology and control points of lime-treated expansive soils. Based on referring to common subgrade construction procedure and combining with lime-mixing technology, it summarizes construction technology of "three stages, six sections, ten procedures" and control points in construction process, and accumulates the construction experience of lime-treated expansive soils roadbed.
