摘 要:长短桩复合地基是近年来逐渐兴起的一种新的复合地基形式,但理论研究和实践仍不完善,需要进行更深入的探讨。通过长短桩复合地基的现场试验,对在刚柔两种基础形式下的长短桩复合地基的沉降变形、桩顶和桩间土的应力、桩土荷载分担比及桩土应力比随荷载变化的规律进行对比分析。研究成果可为长短桩复合地基理论研究和优化设计提供有益的参考。Recently, long-short-pile composite foundation as a new type of composite foundation is developed. But theoretical study and experience still need to be discussed deeply. A field experiment on long-short-pile composite foundation with prestressed high strength concrete (PHC) pile was carried out. The magnitude of the stress between pile and soil, pilesoil stress ratio ,pile-soil load-sharing ratio and settlement and their variation with the load under rigid foundation or flexible foundation were measured and comparably analyzed. The research production can provide valuable reference for the theoretical study and optimization design of long-short-pile composite foundation.
