轻质泡沫混凝土在高填方路基填筑工程中的应用

Application of Lightweight Foam Concrete in High Embankment Subgrade

现今轻质泡沫混凝土应用越来越广泛,在高填方路基工程中,若直接采用土石回填,则竖向压力较大,对底部承载力要求较高。面对基底承载力较低或者基底存在老旧而无法承受巨大土压力的结构物时,轻质泡沫混凝土就显示出了其自身重量低的优势,用其置换回填土,则在高填方路基工程中可以有效减轻竖向荷载,避免对底部结构物造成破坏。

Nowadays？the application of lightweight foam concrete is more and more extensive. In the high embank-ment subgradc project,if earth ＆ rock backfill is directly used,the vertical pressure is large and the bearing capacity of the bottom is higher. Lightweight foam concrete exhibits its own low weight advantage in the face of a lower substrate bearing capacity or a structure that is old and can not withstand the enormous earth pressure. With its replacement backfill,subgradc works can effectively reduce the vertical load.
