| 中文摘要: |
| 粉煤灰是一种环保型的轻质路堤填料,高速公路路堤填筑采用粉煤灰,具有节约耕地、工后沉降小、造价低.文章结合粉煤灰的化学成分和物理力学性质,分析了粉煤灰路堤设计控制要点,即做好防水和排水.同时,提出了粉煤灰路堤施工控制要点,即压实层厚度的控制、含水量的控制、摊铺与碾压的控制和路堤接头搭接的控制. |
| 英文摘要: |
| Fly-ash is an environmentally-friendlly light embankment filling which could save farmland,minish post-comstructien settlement and reduce cost.This paper analyzed the points of fly-ash embankment design from its' chemical constituents and physical property,which are the measures of separating water and drainage.At the same time,this paper suggested that thickness of layers,water content,paver and rolling,and embankment joint must be well controlled in construction. |
