... Abstract The effective stress principle of Biot's consolidation theory is first introduced into deformation reinforcement theory to model directional hydraulic fracturing. The unbalanced force considering the effective stress of fluid is derived and a more effective vector type criterion...

... the associated vector to the pole of the representative plane (mean vector) and the variation in degrees from this vector, respectively. To decide which type of PDF should be used, it is necessary to do a form test and observe if the data describe a cluster or a girdle. In this paper, preliminary results...

...). This aspect is extremely important to guarantee the tunnel functionality, since deformations that started during excavation may continue long after the tunnel construction is completed (Paraskevopoulou & Diederichs 2017). deformation rad array installation vector instrumentation application...

... by introducing in-situ stress information. We can reject candidate focal mechanisms which are consistent with first motion but not consistent with in-situ stress by checking two conditions. 1) consistency between shear vector estimated from in-situ stress and the rake from first motion analysis, 2) state...

... Abstract Vector analysis for prism displacement proved to be a more effective way to interpret the data of topographic survey and the case as the visual aproach contributes to an easier interpretation by the geotechnical engineer. It also serves as a tool to study and interpret the mechanism...

The advantage is that physical phenomena happened on different orientation, such as crack opening/closing or frictional slip can be directly reflected in the constitutive law, which facilitates its formulation...

... training. In SOM, each neuron is presented by a weight or prototype vector, which has many components as the dimension of the input space (i.e. as the number of input variables). The batch training algorithm was used to train the SOM. In this study, during batch training the sample vectors of the input...

As long as those coefficients are components of a symmetric second-order tensor, there are three mutually perpendicular directions, in which the variances reach...

... . The displacement vectors were combined to create a pseudo 3-D displacement map of the slope. The data collected demonstrates that an improved understanding of the 3-D kinematics of a large rock slope can be achieved using advanced state-of-the-art monitoring techniques.
