随着我国高速公路建设的快速发展,高速公路的工程质量日益受到人们的关注。由于高速公路路基填筑普遍较高,地基需承担着车辆荷载和比一段公里大得多填土荷载的双重压力,所以高速公路地基的强度和稳定性不能不引起公路技术人员的高度重视。特别是对可液化地基采取措施进行处理,来降低可液化程度,提高路基的整体稳定性尤为必要。目前处理可液化地基的方法主要有强夯振冲碎石桩、砂桩等,且主要在工业和民用建筑方面应用较多。
With the rapid development of highway construction in our country, the project quality of expressway is paid more and more attention by people. Due to the generally high embankment filling of expressways, the foundation needs to bear the dual pressures of vehicle load and filling load much larger than a kilometer. Therefore, the strength and stability of expressway foundation can not but cause highway technicians to attach great importance. In particular, liquefiable ground to take measures to deal with, to reduce liquefaction, improve the overall stability of the roadbed is particularly necessary. At present, there are mainly methods of handling liquefiable ground such as dynamic compaction vibro-replacement stone column and sand pile, etc., and are mainly applied in industrial and civil buildings.
