摘要:
为了研究打(压)桩时桩侧土体液化导致的桩土相对滑移对桩基临界荷载的影响,采用部分滑移模型,将桩周土分为桩土滑移区域和结合区域,并将二区域的应力分别表示,根据桩土滑移区域和结合区域的应力和荷载的连续性,得到了桩土滑移段的长度,可用以对桩基临界荷载进行修正.结果表明,桩土相对滑移对桩基临界荷载影响较大.
Abstract:
The partial slip model is used to analyze the effect of soil-pile slip on the critical load of pile. The soil is divided into slip zone and bond zone, and the stresses of soil are expressed separately. The slip length is deduced by the continuity of stress and load in the slip zone and bond zone. The slip length can be used to correct the critical load of pile. The results show that pile-soil slip deduces the critical load of pile.
