摘　　要：载体桩由混凝土桩身和载体两部分组成,载体桩承载力高的原因在于桩端通过夯实填料挤密桩端土体形成载体,载体相当于扩展基础,上部荷载通过桩身传递到载体,最终传递到载体下持力层。载体桩夯实填充料可用碎砖、碎混凝土块、水泥拌合物、碎石、卵石及矿渣等,可以消耗大量的建筑垃圾,将质量、成本、环境效益有机结合。The carrier pile is composed of a concrete pile body and a carrier.The reason for the high bearing capacity of the carrier pile is that the pile end is compacted with rammed filler to form the carrier.The carrier is equivalent to the extended foundation,and the upper load is transferred to the carrier through the pile body,and finally to the lower bearing layer of the carrier.The carrier pile compaction filler can be broken bricks,broken concrete blocks,cement mixtures,gravel,pebbles and slag,etc.,which can consume a lot of construction waste and organically combine quality,cost,and environmental benefits.
