Abstract: This paper introduces a new double cell triaxial system (DCTS) for continuous measurement of the volume change of an unsaturated or saturated soil specimen in triaxial test. The DCTS overcomes two critical shortcomings of the conventional triaxial system and the existing modified triaxial cells.It is found that the relative error for the test result of the new DCTS is less than 1.93%. The calibrated results using both the solid copper specimen and the saturated marine clay specimen show that the DCTS is accurate and reliable for continuously measuring the volume changes of unsaturated or saturated soil specimens during consolidation and compression.
介绍一台新双室三轴仪用于非饱和土体积变化的连续测量和三轴压缩试验。该双室三轴仪是对现有的内置开顶圆筒三轴仪和双墙三轴试验仪的重大改进 ,克服了存在的缺点。试验结果表明 ,体积测量相对误差不超 1.93 % ,该双室三轴仪能可靠和相当准确地自动测量土样三轴试验中的体积变化。
