title = "Evaluating foliation tensile strength of metamorphic rock by using pull-off test",
abstract = "The tensile strength of rock is an important property of rock engineering. However, the measurement of tensile strength of rock is often overlooked due to difficulties of specimen preparation and accuracy of testing result. This study adopted the pull-off test to measure the foliation tensile strength of metamorphic rock, including slate, green schist and black schist. Compared with contemporary tensile tests, this method is relatively simple and effective, with easy specimen preparation. Besides, this approach can be conducted not only in the laboratory but also in the field, which is quite useful for evaluating the rock slope stability. This study suggested the procedures of sample preparation and testing as well. The test results indicate that the black schist exhibited the greatest tensile strength, and the slate had the lowest strength. Besides, the slate exhibited significant wetting deterioration. To examine the failure patterns, the failure planes of all specimens occurred on the foliation planes, indicating reasonable failure patterns.",
