碎石桩复合地基检测分析

The Monitoring Analysis on Rushed Stone Pile Composition Foundation

结合南京钢铁集团新钢铁厂碎石桩复合地基工程实例,从桩身的密实性和连续性、桩体周围土的隆起量以及桩间土挤密效果3个方面对碎石桩复合地基进行检测分析。

The article analysis the rushed stone pile composite foundation through the monitoring on the density and continuity of pile, the heave of the soil around the pile and the compaction effect of the soil between the piles. The density of the top of piles is commonly lower than that of the bottom of piles and the fault and shrinkage piles do not exist. It appears surfaces subsidence, which is averagely up to 134 cm. According to the statistics and the comparing of the index of the physical and mechanical properties of every strata soil, the vibration and the compaction effect of piles on the soil is excellent.
