摘要
在现代高速公路建设中,不可避免地会遇到处理软弱地基的问题,处理此问题的方法有多种,CFG桩复合地基法是其中行之有效的手段之一。以广梧高速公路CFG桩复合地基处理为实例,对复合地基承载力、沉降、稳定性进行了理论计算,得出软基路段采用CFG桩处理,可以提高路基承载力,减少沉降,并能提高路基的整体稳定性。
The problem of disposing the soft soil foundation will appear inevitably during the construction of modem expressways.There are many ways to dispose the soft foundation,one of which is CFG pile technology.Taking the CFG pile technology in Guang-Wu Expressway for example,the theoretical calculations are made for the bearing capacity,settlement and stability of the composite foundation,and the results show that this method could increase the bearing capacity,decrease the settlement and strengthen the monlithic stability of soft soil foundation.
