| 摘 要： | 针对上海虹桥机场扩建工程飞行区场地的浅层地基特点,采用"高真空降水+山皮石垫层+冲击碾压"组合法对其进行地基处理,通过静力触探、标准贯入试验和地基反应模量测试,结果发现:该地基处理方法有效的提高了地基的整体性和承载力,控制不均匀变形,并且处理后的地基能够满足机场扩建的设计要求。同时该地基处理方法具有经济效益好、施工周期短等特点。

| Abstract: | Against the characteristics of shallow foundations in the expanded airfield site of Shanghai Hongqiao Airport,the ＂high vacuum precipitation ＋ stone cushion＋ impact-rolling method ＂ Combination treatment has been employed to deel with the foundation,through the CPT,SPT and modulus of the foundation reaction,the result shows that this treatment improve effectively the integrity of the foundation and bearing capacity,control ling unequal deformation,and the improve soil foundation can meet the design requirements of airport extension.meanwhile,the foundation treatment method has the characteristics of good economic benefit,short construction period. |
