A New Method to Estimate Rock Mechanics Composed both the Dynamic and Static Test Means

The reasonable estimate of rock mechanics is extremely important to the design of hydraulic fracture, but the direct triaxial test is a high consumption of time and money. The relation between the dynamic rock mass parameters and the static ones could be used to establish a new method to assess rock mechanics. This new method which was composed by some formulations generated by the well logging data and the Hoek-Brown criterion with the iterative computation way could provide calculated GSI, Young modulus and Poisson ratio data. These data has a little deviation, less than 10% which can be acceptable in project scope, with triaxial test value of rock core. As a result, this method has been proved to be easy and credible to use.
