摘要
土石混合料作为一种填料,越来越广泛地被应用于工程实践,尤其是公路路基工程中。国内外学者对土石混合料的物理力学性质、压实特性和土石混合路基修筑技术已进行了大量的研究,但由于这些研究尚处于初级阶段。因而,仍不能满足工程实践的需要。笔者对不同石质类型、不同比例土石混合料的物理力学性质,土石混合料的分类、工程分级和性能评价,土石混填路基的均匀性及其强度与变形规律,土石混填路基的设计理论和设计方法。土石混填路基施工工艺及质量控制方法等方面进行深入系统的分析。提出了目前研究存在的问题及其解决的初步方法。
Soil-stone material is used widely in many projects recently, especially in expressway construction. At the present time, a lot of study has been carried out on physical properties, mechanical properties, compacting property and soil-stone embankment constructing technology, but all the study results can't direct execution of works effectively. Studies in compaction property, compaction effect detecting ways and semimetal calculation have done little work. If well settle all the problem mentioned above, compaction effect, classification, sedimentation deformation, roller compaction technology and compaction effect measuring should be studied further more. In this paper, based on collection data, we analyze the study results and find out the defects, and present the means for research.
