摘要
采用单轴拉伸法研究了影响土的抗拉强度测试方法的因素,探讨了加荷速度、样品直径、高径比对土的抗拉强度测试值的影响,试验结果表明,样品直径对土的抗拉强度测试结果影响不大,加荷速度和高径比是影响土的抗拉强度的测试结果的重要因素。给出了单轴拉伸法测试土的抗拉强度的加荷速度和高径比的建议值。
This paper studied factors affecting measurement of tensile strength of soil using uniaxial tension, discussed the effect of loading speed, sample diameter and height-diameter ratio on measurements of tensile strength, and the results indicated that sample diameter has little to do with tensile strength measurements, and loading speed and height-diameter ratio play a major role in affecting the measurements. Proposed values for loading speed and height-diameter ratio were given for measuring tensile strength of soil using uniaxial tension.
