| Abstract: | For correct understanding and precise measurement of the tensile strength of soil, a horizontal earthwork elongation apparatus with a single axis is developed based on the box shear apparatus. The apparatus can be used for the measurement of axial strain and stress of samples, and for the observation of crack opening during the stretching of samples. Tests show that the apparatus is an effective device for the study of soil tensile behavior and it is convenient in operation, stable in performance, and high in precision. |
