本文介绍了东海塘试验堤的分期填筑预压、现场测试及分析计算成果。表明地基的实测沉降量大于常规计算的沉降量;实测孔隙水压力证明地基浅层已发生排水固结,其消长规律可用以判断地基的固结度;地基强度增长的估算,用改进的单向排水固结计算方法,算得的强度与实测十字板强度比较接近;稳定分析采用分期分区的实测强度,经过电算,能反映实际情况。本文还介绍用有限元法计算变形和孔隙水压力得到的较好结果。最后对其他有关问题也进行了讨论。
This paper introduces the staged preloading of Donghaitang embankment, field test and analysis and calculation results. The results show that the measured subsidence of foundation is larger than that of routine calculation. The measured pore water pressure proves that drainage consolidation has occurred in the shallow ground, and its growth and decay can be used to judge the consolidation of foundation. Drainage consolidation calculation method, the calculated strength and the measured intensity of the cross plate is closer to; Stable analysis of the measured intensity of the staging area, after the calculation, can reflect the actual situation. This article also describes the better results obtained by using finite element method to calculate deformation and pore water pressure. Finally, other related issues have also been discussed.
