| 摘 要： | 冻害地基上采用EPS块体取代填土来修筑路堤,具有防冻性能好、稳定性好、施工快速简便等优点。现场实验结果表明采用EPS轻质路堤降低了路基土的冻结深度,从而消除了路基冻害,改变了路基土的温度状况。

| Abstract: | Embankment is built with EPS block instead of filling at foundation injured from freeze,having merits of better antifreezing performance,better stability and fast and simple construction.Field experiment result shows that lightweight embankment adopting EPS reduces freezing depth of subgrade soil,so subgrade freeze injury is eliminated and temperature condition of subgrade soil is changed. |
