摘要
总结和阐述了小孔扩张理论在孔收缩理论(典型的隧道开挖)和孔扩张理论(典型的沉桩施工、静力触探等)两个方面近年来的相关研究成果。在隧道开挖研究方面,主要从本构模型(黏弹性或黏弹塑性模型、弹塑性模型)方面展开相关介绍;在沉桩施工、静力触探等方面,主要从饱和土体和非饱和土体两个方面对扩孔问题进行了相关介绍。最后指出小孔扩张理论未来需要进行研究的方向,从而进一步完善该理论。
This paper summarized the recent research results of cavity expansion theory in two aspects:cavity contraction theory(typical tunnel excavation)and cavity expansion theory(typical sunken pile construction,static contact,etc.).In tunnel excavation,the research were mainly introduced from the aspect of intrinsic model(viscoelastic or viscoelastic-plastic model,elastoplastic model);in sunken pile construction and static contacting,the expansion problems were introduced from two aspects of saturated soil and unsaturated soil.Finally,it pointed out that the future research direction of cavity expansion theory was needed to further improve the theory.
