石灰改良全风化花岗岩路基填料的试验研究与施工工艺

Experiment Study of Modifying Roadbed Filler of Seriously Weathered Granite by Blending Lime and Technological Process of Construction

针对风化花岗岩的特殊物理、工程性质 ,首先提出了不同情况下的处理办法 ,但重点在于通过试验研究 ,总结出石灰改良全风化花岗岩的适用范围 ,以及不同地质情况和施工区域下的配比推荐值 .文中提出的一套行之有效的施工工艺 。

Aimed at the special characteristics of engineering and physics of weathered granite, several different measures are put forward according to the actual construction situation. Nevertheless the focal points of this article are,through testing and research on seriously weathered granite modified by lime,to find the appropriate range in which dealing with fully weathered granite by blending lime is most rational.At the same time, the corresponding blending ratios just for reference are also summarized. The effective construction technology proposed in this article has been examined in the construction of Lin Chang expressway.
