【摘要】 塑料排水板为竖向排水体的排水加固法在软土地基处理中应用广泛。在塑料排水板的施工和工作过程中,需要考虑由于施工引起的涂抹效应和土体变形等引起的井阻效应,对排水板工作性能和加固软基效果的影响。本文通过某堆场的数值研究,分析了不同涂抹比、渗透比和纵向通水量情况下的堆场地基加固效果,得到了一些有意义的结论。更多还原

【Abstract】 Prefabricated vertical drains(PVDs) have been used successfully in many soft soil improvement projects.The smear effect due to construction of PVDs and well resistance due to settlement of soil need to be taken into consideration in evaluating long-term performance of PVDs.A parametric study is performed to investigate the effects of the smear zone and well resistance,and some useful conclusions are drawn.更多还原
