| Abstract: | The abnormal qualities of vibro-pile of Xiamen typical marine soft soil foundation were detected respectively by the means of bearing capacity of pile testing and pile integrity testing. According to the charaetertsucb soft soil foundation and the construction technology of vibro-pile, the main influential factors of the quality for abnormal con- struction quality of vibro-pite were systemically analyzed. The results showed that the main quality problems of vibro-pile of Xiamen marine soft soil foundation were pile breaking and necking, and rational suggestions were taken for their solution. |
