【摘要】 研究表明 ,砂性地基中挤密砂石桩的加固效果与土层侧向加密作用、施工时土层竖向下沉影响、上覆土压力、土中细颗粒含量、时间等有关。常规设计方法只考虑了其中一个或几个因素的影响。提出了能同时考虑这五因素影响的砂性地基挤密砂石桩的设计方法。更多还原

【Abstract】 Research shows that the consolidating effect of the sand compaction piles in the sand foundation is related to the factors such as lateral compacting action of the soil layer,vertical subsidence influence of the soil layer when constructing,soil pressure on it,fine particle content in soil and time. The conventional design method only considers one or several factors. The new design method is given in the paper,with which the five factors of influencing sand compaction pile in sandy foundation can be simultaneously considered.更多还原
