摘要
山岭多丘地带的高速公路施工中,针对深挖的土质路堑,其路床由于地下水或毛细水的影响,弯沉和压实度等技术指标难以达到规范要求,势必会影响今后的路基乃至路面的稳定。本文对大面积夯压组合施工的深填填石场地施工进行了分析研究,最终形成大面积夯压组合深填填石场地施工技术,本技术具有路基稳定性好、施工效率高等优点,特别适合山岭重丘区土质路堑基底换填施工工程。
In the construction of expressway in mountainous and hilly area,it is difficult for the road bed to reach the standard requirements due to the influence of underground water or capillary water,bending and sinking,compaction degree and other technical indexes,which will inevitably affect the stability of roadbed and road surface in the future.This paper analyzes and studies the construction of large area compaction combined with deep filling stone site,and finally forms the construction technology of large area compaction combined with deep filling stone site.This technology has the advantages of good subgrade stability and high construction efficiency,and is especially suitable for the construction project of changing the foundation of soil cutting in heavy hilly areas.
