摘要
本文简要描述多功能岩石三轴流变仪的设计和加工.它可以研究围压、空隙压力、载荷时间和温度对岩石性状的效应、各种流体的软化效应及岩石的渗透性。在这种类型仪器的基础上,我们将进一步设计、加工三轴仪的系列产品,为国内外不同试验研究目的提供不同规格的三轴设备. 本文报导了在不同围压、空隙水压力、加载时间及温度下完整岩样的一些典型试验结果.作者将水压力变化特性与岩石蠕变、扩容及强度的性状相关联,并对岩样的体积变化机制做了扼要的分析,还介绍了水对岩石力学性质的软化作用.
This paper deseribes a multipurpose rock triaxial rheological apparatus, its design and construction Considering the effect of confining pressure, pore pressure, temperature and time, it can be used to study behavior of rocks, softening of liquids and permeability of rocks, On the basis of this apparatus, series of triaxial apparatuses will be developed and supplied for both native and foreign users.
Some results of typical test including confining pressure, pore water, time and temperature effecting on rock specimens are presented, The relation between pore pressure and characterisfics of creep, dilatancy and strength are discussed, The mechanism of volume change and effect of water on mechanical properties of rock are analysed
