砂卵石换填地基在洛(阳)南新区高层建筑中的应用

Application of Foundation Replacement by Sandy Pebble for High-level building in Luonan New Zone of Luoyang City

摘要:

从粗粒土振动压实特性、砂卵石地基承载力特征及作用三方面对砂卵石换填地基进行了分析总结,通过工程实例证明人工换填的砂卵石地基承载力较高,沉降量小且均匀,能够满足高层建筑基础设计要求,适宜在洛(阳)南新区高层建筑地基处理中推广.

Abstract:

Analysis was made on sandy pebble replacing foundation in the character of vibrating compression, bearing capacity of sandy pebble ground and its function. It was proved that bearing capacity of artificial sandy pebble replacing foundation was better with small and uniform settlement, and was suitable to be applied for high-level buildings in Luonan new zone of Luoyang City.
