摘要

控制沉降和不均匀沉降是深厚软土地基上多层建筑工程设计的关键问题。以温州某康居工程为背景，把预制管桩结合水泥搅拌桩这种新型的刚柔性桩复合地基运用于该小区的地基处理，通过大型现场静载试验，研究了该类复合地基沉降随荷载变化规律，分析了刚性桩和柔性桩应力比、刚性桩土应力比、柔性桩土应力和荷载分担百分比随荷载变化的发展规律。研究表明，两种桩和土应力比值在静载试验中随荷载增加其值变化不大，充分发挥了桩间土的承载力特性。所得结论可为该类地基进一步的理论研究及工程设计提供有益的参考依据。

Abstract

The settlement and uneven settlement are the key problems subjected to the design theory for tier buildings on deep soft ground. Taking an important project in Wenzhou City as background

the application of the composite foundation of pre-cast tubular pile and mixing cement pile was introduced. Based on the in-site loading test

the major engineering characteristic of this type of composite foundation was studied. Settlement

the stress ratios and load ratios of piles to soil were analyzed carefully. The results show that the stress ratios of tubular piles to cement mix pile and the stress ratios of piles to soil vary little during the load testing

the bearing capacities of soil can exploit quite fully. It will be provided as references for future design and research.
