Abstract
Compared to the compressive or shear strength of soil, its tensile strength is generally assumed to be zero, or insignificant, in geotechnical engineering practice because of its relatively small value and lack of a satisfying laboratory technique. The tensile strength of soil is, however, an important parameter in the design of geosystems, where tensile cracks contribute to progressive erosion or landslides in excavation, slopes, dams, highway embankments, riverbanks, hydraulic barriers, and other earth structures. In this paper, a recent development of the indentation test is presented. The theoretical framework is re-evaluated followed by a series of test results on lightly cemented sand.
