| 摘 要： | 水泥搅拌桩和塑料排水板联合使用的组合型复合地基具有利用搅拌桩增强软土地基的强度,利用塑料排水板加快地基的固结进程的特点,因此对于处理深厚饱和软土地基具有很强的推广价值.由于其平面布置多为梅花形,整体上呈非对称性,其固结特性理论分析的难度较大.为了从理论上进行该组合型复合地基固结特性分析,本文首先针对其排水系统进行了合理...

| Abstract: | The combined composite foundation with cement-mixing piles and prefabricated vertical drain has the characteristics of enhancing the strength of soft soil through soil-cement piles and promoting the consolidation process of foundation through drainage system.Therefore,it has high promotion value for dealing with deep saturated soft soil.The distribution of piles and vertical drain in this method is usually in equilateral triangle pattern.Due to its unsymmetrical distribution in plane,it is not easy to get t... |
