Abstract |
|
|
| In this study, we used the Ordinary Point Kriging for predicting the spread of shear strength of rock at a site in an unobserved location. Based on the nature of rocks, the rock quality index is measured by rock shear strength with less strong rock properties which has a weaker of the strength of rocks to support the load and become a weak field. The calculation of the spread of the shear strength of rock can be made using GStat-R program in R software to get accurate results. In the calculation of prediction using the kriging method, we can use gstat library, sp library, Rcmdr library and several algorithms in GStat-R and apply them to the data to get a prediction of shear strength index of deployment at an unobserved location. |
