It is important to evaluate rock strength in order to check stability of a rock slope or to design a structure built on rock. However, test methods used for the evaluation have some difficulties since rock samples provide various deviation of strength due to micro cracks in the samples and teat errors, Also, reliable data have not been accumulated for the rock strength in Korea. Therefore, simple teat methods that can be used easily for investication of rock strength in field or in laboratory are not provided sufficiently yet. This study is to investigate variation of the rock strength due to the degree of weathering and to evaluate the degree of weathering by types of rocks, by using data that have been obtained for several years. Therefore, it is possible to provide a relationship between several rock strength values by performing tests such as uniaxial compression teat, point load test, schmidt hammer teat, absorption ratio best and slaking durability tests. The equations of relationships that can be used to estimate rock strength by using simple test methods in field and in laboratory are proposed.
