软土地基中刚柔组合桩型应用事故及处理实例分析

Analysis of Accident in Application and Treatment Example of Rigid-flexible Pile Type in Soft Soil

本文通过对一例工程的分析 ,在软土地基上采用钢柔组合桩型来处理地基 ,钢性桩、柔性桩及桩间土受力不合理 ,沉降速度偏快 ,沉降量大 ,在工程中应慎用。

By analysis of a example engineering,this paper finds rigid pile、flexible pile and the soil between piles have disadvantage of forcing when rigid-flexible pile type is used to treat foundation in soft soil,because their settlement velocity is faster and their settlement comes to a large amount,so it is suggested that it should be carefully used in engineering.
