摘　　要：高速公路路基填筑普遍较高,地基主要承担填土静荷载,特别是对可液化软基采取措施进行处理,提高地基承载力和稳定性尤为必要。目前处理可液化地基的方法主要有强夯碎石桩,砂桩等,而强夯置换工艺在工程建筑领域的应用还是比较少见,造价相对来说较低。麦盖提至喀什高速公路第四合同段采用强夯置换方法进行加固地基处理,效果明显,达到规范要求。Generally high embankment of highway subgrade and foundation mainly undertakes filling static load,especially to take measures can be liquefied soft foundation processing,improve the foundation bearing capacity and stability is necessary. The disposal method of liquefiable foundation is mainly gravel pile and dynamic compaction sand piles,etc.,and application of dynamic compaction replacement method in engineering construction field is rare,relatively low cost. Markit to kashi highway contract section 4 to reinforce foundation treatment by dynamic consolidation method,obvious effect,to meet the specification requirements.
