摘要
某高速公路沿线大部分路段为软土路基。其中一桥头段位于深厚软土路基上,根据工后沉降的要求,采用了带桩帽的预应力管桩+土工格栅垫层的处理形式。经过对现场试验数据分析,表明该种处理方法效果较好,具有处理深度大、质量易保证、工后沉降小等突出优点,可以作为类似软基处理设计时参考。
The highway is built on the soft foundation. To meet the standard of post-construction settlement, prestressed pipe piles combined with geogrid reinforcement cushion are applied to improve the foundation of approach embankment. The field observation shows that the new method to improve soft foundations is available. It has a guiding significance to the design of similar highway.
