摘要： A testing apparatus for determining tensile strength of soft rock and soil tests a sample having a central hole. A drawbar device holds the sample in a central, upright position. The drawbar device has two main parts, namely the left fixed part and the right lateral movable part. A fixed frame connects to the left fixed part and a lateral movable frame connects to the right lateral movable part. The drawbar device has two arms. The sample is positioned on the central pull rod through the hole of the sample. A tension sensor and a displacement sensor detect the tension force and displacement as the sample is pulled apart. A data analysis module calculates a tensile strength based on the tension force and the displacement by the equation: σt=500 αFmax/(R−r)h.
