中文摘要:利用夯扩灌注桩对桩端持力层的加密作用,可解决水下填筑问题,利用粉煤灰的可压密性和夯扩灌注桩承载力高的特点,可大幅提高复合地基承载力,减少工程投资。以河南洛阳某高层建筑为例,介绍了粉煤灰垫层和夯扩灌注桩组成的刚性桩复合地基在高层建筑地基中的应用。

Abstract:Ram-compaction pile can tamp bearing soil layers to densify the stratum in water. The bearing capacity of composite foundation can be greatly increased and engineering investment can be reduced by use of compressibility of flyash cushion and high bearing capacity of ram-compaction pile. The composite foundation, made up of ram-compaction rigid piles and fly-ash cushion, is introduced with the application of a high-rise building in Luoyang, Henan.
