Deformability Evaluation of Soft Rock Foundations for Dams Considering.

evaluation of rock mass deformability

One of the most important effective parameters in design of engineering structures is deformability of rock mass. Benchmark of rock mass deformability is the deformation modulus that directly or indirectly obtained. Since the determination of rock mass deformation modulus indirect method by in-situ tests is time-consuming, costly and difficult from executive operations aspect, so it’s correctly...

Optical deformability of soft biological dielectrics.

Two counterpropagating laser beams were used to significantly stretch soft dielectrics such as cells. The deforming forces act on the surface between the object and the surrounding medium and are considerably higher than the trapping forces on the object. Radiation damage is avoided since a double-beam trap does not require focusing for stable trapping. Ray optics was used to describe the stres...

A new approach for assessing stability of rock slopes considering centroids of weak zones

The intersection lines between discontinuity surfaces and their intersection points on the visible surfaces of any engineering structure may be the instability indicators. This paper describes a new approach to modelling the intersecting lines and points that would provide the first evaluation of any instability in an engineering structure characterized by the failure modes. In this work, the i...
