【摘要】 对湿陷性黄土地基环境下大型建筑物不均匀沉降机理进行了深入分析,提出了"旋喷桩加固法"处理该类地基事故的策略,详细分析了地基产生不均匀沉降的成因,对地基处理设计、施工参数确定及施工控制等进行了讨论。实际应用表明,采用该方法处理由多因素造成的地基事故,是一种行之有效的方法。更多还原

【Abstract】 The mechanism of nonuniform settlement of largescale building with collapsible loess ground was deeply analyzed and its treatment strategy was presented in this paper. The chemical churning pile, as a suitable method, was used to deal with such ground accident. The authors analyzed the cause of formation of nonuniform ground settlement, discussed the factors of foundation design and construction control. Practice shows that the chemical churning pile is an effective way to deal with similar ground settlement accident caused by multifactor.更多还原
