| 摘 要： | 在阐述电渗复合真空预压法加固原理的基础上,依托湖北省离岛梁子湖国家水生态展示馆吹填软基处理工程,进行电渗复合真空预压现场试验,对导电塑料排水板的性能和电渗排水加固效果进行实地验证。现场试验结果表明:经过28 d的电渗复合真空预压法加固,地基土土体物理力学性质指标和承载力得到明显提高;使用导电塑料排水板进行的电渗复合真空预压处理吹填土不仅能够缩短工期、节省能耗,还能够获得理想的加固效果。 |

| Abstract: | Based on the consolidation mechanism of the combined electroosmosis-vacuum preloading method, a field test was conducted on the hydraulically filled soft foundation treatment project in the Liangzi Lake Aquatic Ecological Exhibition Hall on Li Island, in Hubei Province. The performance of electric vertical drains(EVD)and the consolidation effect of electroosmosis were evaluated. The field test results show that the physico-mechanical properties and bearing capacity of the foundation soil are improved significantly after a 28-day treatment. The electroosmosis-vacuum preloading method using EVD can not only reduce the construction time and energy consumption, but also achieve the ideal consolidation effect. |
