软件简介：	砂土非共轴性的空心扭剪实验研究英文版作者：蔡燕燕著出版时间： 2015年版内容简介岩土材料在主应力增量和主应变增量上具有非共轴性，其重要性在岩土工程领域中被广泛重视。本书利用hca（空心扭剪仪）进行了一系列砂土的非共轴力学试验，并且从砂土非共轴性的表象规律、发生条件和机理、影响因素等方面进行了深入阐释。本书内容包括：文献综述，试验方法介绍，单调加载试验研究，纯剪试验研究，联合加载试验研究。目录 abstract acknowledgements list of symbols chapter 1 introduction 1.1 background 1.2 research objectives 1.3 outline of the book chapter 2 literature review 2.1 introduction 2.2 non-coaxiality of soil behaviour 2.2.1 definition of non-coaxiality 2.2.2 previous studies on non-coaxiality 2.2.3 previous numerical studies on non-coaxiality 2.3 hollow cylinder apparatus 2.3.1 introduction 2.3.2 principles of hollow cylinder testing 2.3.3 stress distribution in hollow cylinder specimens 2.3.4 specimen geometry 2.3.5 membrane penetration errors 2.3.6 previous experimental studies using hca 2.4 previous studies on non-coaxiality of soil behaviour using hca 2.5 summary chapter 3 experimental methodology 3.1 introduction 3.2 ncg hollow cylinder apparatus 3.2.1 introduction 3.2.2 equipment setup 3.2.3 loading system and measuring instrumentation 3.2.4 control software 3.3 tested materials 3.3.1 index properties 3.3.2 particle shapes 3.4 testing procedures 3.4.1 specimen preparation 3.4.2 saturation and consolidation 3.4.3 test control 3.4.4 stress paths 3.5 equipment evaluation 3.5.1 preliminary experiments 3.5.2 repeatability of test results 3.5.3 hollow cylinder test versus triaxial test 3.5.4 membrane penetration error correction 3.6 summary chapter 4 monotonic loading tests 4.1 introduction 4.2 test details 4.2.1 initial conditions 4.2.2 stress paths 4.3 general soil behaviour 4.3.1 series f-d: dense sand 4.3.2 series f- m: medium dense sand 4.3.3 discussion and comparison 4.4 non-coaxial soil behaviour 4.4.1 series f- d: dense sand 4.4.2 series f- d: medium dense sand 4.4.3 discussion and comparison 4.5 summary chapter 5 pure rotation tests 5.1 introduction 5.2 testing procedures 5.2.1 testing conditions 5.2.2 stress paths followed 5.2.3 variations of stresses 5.3 tests on portaway sand 5.3.1 general soil, behaviour 5.3.2 non-coaxial behaviour 5.4 tests on leighton buzzard sand 5.4.1 general soil behaviour 5.4.2 non-coaxial behaviour 5.5 comparison and discussion 5.6 summary chapter 6 combined loading tests 6.1 introduction 6.2 testing procedures 6.3 general soil behaviour 6.3.1 stress variation 6.3.2 strain variation 6.3.3 effect of density 6.4 non-coaxial soil behaviour 6.5 comparison and discussion 6.6 summary chapter 7 summary and conclusions 7.1 summary 7.1.1 background on non-coaxiality 7.1.2 reason to study the non-coaxial soil behaviour 7.1.3 experimental techniques 7.2 conclusions 7.2.1 behaviour under monotonic loading 7.2.2 behaviour under pure rotation of a 7.2.3 behaviour under combined loading 7.3 recommendations for future research 7.3.1 update of the experimental techniques 7.3.2 experimental work list of tables list of figures references
