桩体水平位移统计分析

在对金东纸业有限公司涂布机车间桩基工程桩位进行全面量测的基础上，对几条曲型轴线的桩体水平位移进行了统计描述，得出了桩频数-桩体位移曲线，通过分析表明：桩体的偏移不仅受本轴线沉桩挤土效应的作用，而且还受临近轴线沉桩和流水作业顺序的影响；桩位越密，轴线间距越小，偏移量越大，桩体的水平位移曲线就趋势而言大至呈正态形式，桩体的水平位移曲线分析对于预制混凝土桩的设计和工程质量控制具有重要的指导意义。

Analysis of Statistics of Pile Body Horizontal Shift

Based on the overall measurement of the construction pile positions of the coating?machine workshop of Jindong Paper Industry Corp.Ltd.,a statistics depiction is drawn out of pile body horizontal shift of a few typical axial traces,and pile frequency curve of the pile body shift is obtained. The analysis shows that pile body shifting is not only caused by the effect of the pressed earth of the sinking pile body of the axial trace,but also affected by the the nearby axial trace sinking pile and the workflow of the process. The denser the pile positions and the shorter the distance of the axial trale are,the greater the offset is. As well as the curve is concerned, the pile body horizntal shift is more or less in the form of orthostate. The analysis of the pile body horizontal shift curve is of great signficance for the design of precast reinforced concrete piles and the quality control of the projects.
