Book excerpt: This project was aimed at: (1) evaluating and developing design methods for laterally loaded drilled shafts socketed in anisotropic rock, (2) Develop a p-y criterion that can be used to analyze the response of drilled shaft socketed into transversely isotropic rock or jointed rock, (3) Develop a new methodology for determining the five elastic constants of a transversely isotropic rock medium using the in-situ pressuremeter test device, (4) Develop a new equation for estimating the transverse isotropic rock shear modulus, (G') using other elastic constants. (5) Develop a new methodology to obtain a p-y criterion using in-situ pressuremeter technique that can be used to analyze the response of drilled shaft socketed into transversely isotropic rock. The hyperbolic p-y criterion for rock proposed in SJN 134137 based on the field test data and extensive theoretical work was further validated using additional load test data. Validation of the proposed p-y criterion of rock was carried out by comparing the predictions of shaft deflections and bending moments using the hyperbolic p-y criterion against actual lateral load tests results. Based on the findings of this study, a complete solution for the design of drilled shafts socketed in anisotropic rock or intermediate geomaterials under lateral loads is provided.
