摘要
本文根据实验和理论分析,提出一种单轴、三轴压缩试验的新的破坏判据,分析其机理是体积或密度连续原则的破坏。指出这一判据有可能应用在这种试验的自动控制上。同时讨论了低围压情况下土样单轴、三轴压缩试验橡皮套产生附加围压的影响及一种计算方法。
Based on exprimental and theretical analysis, the authors propose a new failure criterion for uniaxial and triaxial compression tests. The mechanism for the failure is disturbance of the volume or density continuity caused by the failure. The criterion will be helpeful to find its application to the automatic control of the above mentioned tests. Moreover, the influence of the confining pressure of the rubber membrane case on the soil uniaxial and triaxial compression tests is also discussed. A calculation method is suggested to correct the calculation of cohesion.
