摘　　要：针对西安某高层住宅楼施工过程中出现的橡皮土、河床土、沙层等特殊土质现象,比对前人研究成果,提出采用换置土层、添加粘土砖等加固存在橡皮土的不良地基,以及在沙带施工过程中填充碎石并洒水增加碎石与原沙土的粘结作用等地基处理措施.对加固后的地基的承载力力学特性进行了现场试验检测.研究结果表明:三标和四标针对同一种类型的不良地基采取的不同措施均能够满足设计要求的承载力,很好地解决了地基土不良反应问题.此处理方案可以经济、有效地加固湿陷性黄土地基.For the treatment of special foundation of rubber soil ,riverbed soil and sand layer of a high -rise residential building in Xi＇an ,the scheme of replacement of soil ,clay brick adding ,filling sand and gravel and watering to increase bonding effect is proposed .Mechanical properties of the bearing capacity of the reinforced foundation is conducted a field test .The results show ：The measures for the poor standard of foundation of the same type meet the design requirements of the bearing capacity ,w hich is a good solution to the problem of adverse soil foundation .This treatment program can be economically and effectively strengthening collapsible loess foundation .
