| 摘 要： | 以南方某污水处理厂现场监测资料为依据，分别采用双曲线法、指数曲线法、Asaoka法推算地基的最终沉降量、分析真空预压的加固效果。通过Terzaghi固结理论反算地基水平平均固结系数，计算值较室内试验值更符合实际，弥补了室内试验的不足。虽然真空预压法在刚性基础软土地基中的加固效果较好，拓宽了其应用领域，但是仍然存在着一定的工后残余沉降量，应在结构设计中预以考虑。 |

| Abstract: | In this paper,we discuss this issue of vacuum preloading used in rigid foundation,by computing the final settlement and analyzing consolidation result.The monitored data from a sewage farm in southern China were processed by three respective methods:hyperbolic matching,exponential matching and Asaoka method.In addition,the mean horizontal consolidation coefficient is back-analyzed by using Terzaghi consolidation theory.The back-analysis of this project is closer to the settlement fact than indoor soil mechanical test.Even though the vacuum preloading sometimes is suitably applied to soft soil of rigid foundation,it has a little residual settlement.All of these should be taken into account in structure design. |
| Keywords: | rigid foundation final settlement Terzaghi theory consolidation coefficient |
