摘要
分析了某防波堤工程软土地基产生弱化的原因及相应工程措施,对塑料排水板的加固效果进行了有限元数值分析。基于固结度等效原则,将三维砂井地基转换为平面应变问题。利用现场实测数据验证了数值模型的有效性,探讨了产生误差的原因。计算结果表明,排水板能够有效缩短软土固结排水时间,减少工后沉降。
The factors that might contribute to the weakening of the soft soils underneath the breakwater dike are discussed and the possible solutions are also presented in this paper.The improvement effect of using Prefabricated Vertical Drains（PVD） has been numerically analyzed.Based on the equivalent degree of consolidation,the three-dimensional problem is converted into plane strain problem.The numerical analyses are validated by the in-situ measurement.
