摘要
针对陇东地区某高速公路K1322+492-K1322+624段路基沉陷病害进行成因分析,采用了干拌水泥碎石桩及注浆加固的路基综合加固技术。通车后对路基沉降进行监测发现,该技术可有效提高地基承载力,且施工简单、快速,与其他地基处理方式相比性价比较高。
This paper analyzes the causes of subgrade subsidence disease in K1322+492-K1322+624 section of an expressway in Longdong.The comprehensive reinforcement technology of dry mixed cement gravel pile and grouting reinforcement is adopted.The monitoring of subgrade settlement after opening to traffic shows that this technology can effectively improve the foundation bearing capacity,and the construction is simple and fast.Compared with other foundation treatment methods,it has high cost performance.
