doi:10.3969/j.issn.1674-0696.2019.01.03

Abstract

Abstract: The research status of true triaxle test of concrete at home and abroad was systematically introduced, including the kinds of concrete, loading apparatus, anti- friction measures, dimensions of specimens, loading paths and failure modes. Some problems in true triaxle test were analyzed and summarized, for example, there were fewer true triaxle tests under strain path and stress-strain mixed path and the corner effect was obvious.The review provides a theoretical basis for the true triaxle test of concrete under complex stress state.

Key words: truetriaxle test of concrete;kinds of concrete, ant-ifriction measures, dimensions of specimens;failure modes

摘要： 系统的介绍了国内外混凝土真三轴试验的研究现状，包括混凝土的种类、加载设备、减摩措施、试块尺寸、加载路径和破坏形态；分析总结了真三轴试验中存在的一些问题：诸如应变路径和应力应变混合路径下真三轴试验较少，边角效应明显等。为复杂应力状态下混凝土的真三轴试验研究提供了理论基础。
