摘要
分析了软土地区采用夯扩桩基础破坏的原因。这些原因包括软粘土侧压力、沉桩引起的挤土效应和超孔隙水压力、桩身负摩阻力和桩的压屈。
The reasons of destructive foundation with compacted base-enlarged piles in soft clay are analyzed. These reasons include lateral pressure of soft clay, influence of compaction of soil and excess pore-water pressure during pile driving, negative friction of piles and pressure yield of pile.
