| 摘 要： | 利用平均固结度普遍解,将未打穿砂井地基转化为等效双层地基,给出了下卧层一维固结解析解,进而求出下卧层的平均固结度。根据该解和现有解,编制计算机程序,给出了几幅考虑c值和土性参数对固结的影响曲线图,评估各解的适用性。研究表明,该解满足工程要求,特别是在PTPB排水条件下能够较好地反映Uz-Tv曲线的真实变化。 |

| Abstract: | The ground by partially penetrated sand drain is turned into a equivalent-double-layered ground with the general solution of the average degree of consolidation;and the analytical solution of 1-D consolidation for the underlying soft layer is given;and furthermore the average degree of consolidation is obtained.Based on this solution and the present existed solutions,these relevant programs are programmed.The influence of c and soil property parameters on the consolidation process is investigated;and the relevant results are prepared in graph forms;and the applicabilities of all these solutions are evaluated.It is shown that the solution in this paper fulfills the requirements of project.Especially in the case of PTPB,the curves of Uz-Tv are more actual which drawn by this solution in comparison with the others. |
| Keywords: | ground by partially penetrated sand drain equivalent-double-layered ground the underlying soft layer average degree of consolidation analytical solution |
