摘要
因昆明新机场为不均匀地基,若直接修建机场跑道,差异沉降不能满足设计要求。采用振动沉管碎石桩对不均匀地基进行处理,并对处理后地基进行沉降计算、沉降观测和原位检测试验,以判别处理后地基的工后沉降和差异沉降能否满足机场跑道的设计要求。结果表明,采用振动沉管碎石桩的处理方法,能够成功解决由地基不均匀引起的差异沉降问题,可为类似工程提供设计参考。
The foundation of the new airport in Kunming City is uneven and the differential settlement can not satisfy the design requirements.We carry out foundation treatment by vibro-replacement stone columns,and also perform the settlement calculation,settlement observation and in-situ test,so as to judge whether the post-construction settlement and differential settlement can satisfy the design requirement of runway.The results show that the differential settlement problems caused by uneven foundation can be solved after treatment by vibro-replacement stone columns.
