摘要: 根据士拱效应理论,通过分析管桩在沉桩过程中士塞的拱效应机理,提出了一种计算土寒效应的新方法,以判 断管桩在沉桩至任意深度时桩内土塞的闭塞程度。用数值模拟的方法进行拱效应分析,得出土塞效应与管桩桩径、 土塞高度之间的关系。实际工程分析表明:该方法对土塞效应的判断、管桩沉桩难度的预测与工程实测数据吻合较 好。

Abstract: According to the theory' of soil arching effect , a new method of calculating the effect of soil plug was proposed by the analysis of the pipe pile arching effect mechanism of soil plug in pile driving. The occlusion degree of soil plug of pipe piles driving in any depth was judged. Soil arching effect was analyzed by numerical simulation , and the relationships between the soil plug effect , pipe pile diameter and soil plug height were obtained. Practical engineering analysis results show that the proposed method is good for the judgment of soil plug effect and the prediction of pipe pile driving difficulty. The data got by the proposed method are in good agreement with actual data

Key words: geotechnical engineering, pi pe piles, soil arching effect, soil plug
