高速公路路基填前冲击压实效果分析

Analysis on the Effecion of Pond Compacting Before Roadbed Filling of Expressway

本文对青银高速公路路基填前碾压采用的冲击压实技术进行了分析，对冲击压实工艺和不同的冲击压实遍数的压实度、沉降量和地基强度进行了总结，提出了合理的冲击压实适用范围。

This paper analyzed the technology of pound compacting of roadbed rolling before filling on Qingdao to Yinchuan Expressway, summed up pound compacting technique, compacting density under different pound compacting times, subsidence and roadbed capaeity, and finally put forward reasonable scope of pound compacting.
