| 摘 要： | 通过理论分析和现场试验研究 ,探讨不同的台背回填材料及不同的压实设备与回填松铺厚度的关系 ,找出最佳匹配方案 ,以及在最佳匹配方案下施工所能达到的台背回填效果。研究表明 ,在连续级配碎石、砂砾、石灰稳定土、石屑几种回填材料中以自然级配砂砾石为最佳台背回填材料。松铺厚度与回填材料、施工工艺、施工设备的最佳匹配是保证台背回填质量的关键。

| Abstract: | According to the theory analysis and field experimental research, the relationship between different backfill and compacting equipment and slackly lay thickness of backfill was studied, the best matching scheme, and the result as well as the economic returns brought by taking the best matching scheme were put forward. According to the research, the natural graded gravel is the best backfill material of graded crushed stone, grit, lime stabilized soil and rock chips.The key factor to guarantee the quality of backfill is the best match of backfill material,construction technics and construction equipment. |
