The Release of Slide7.0 The release of Slide 7.0 marks one of the most ambitious Rocscience program upgrades in recent years. Slide, a 2D limit equilibrium slope stability and groundwater analysis program for or rock slopes, is due to be released this December! It is already available for ordering in the Online Store!

The release of Slide 7.0 encompasses a multitude of Soil Profile Modeling powerful new features, including, but not limited to, multi- The Soil Profile option is an extension of geometry scenario modeling, option to enter borehole data to define modeling capabilities in Slide. It allows you to define a soil profile, advanced statistical correlation, Newmark master profile of your material boundaries (e.g. geological seismic analysis, and integration with our new pile analysis or soil profile) and ground surface. The profile is then used software, RSPile. We have created seven new tutorials to as a base template, over which you can use the regular walk you through some of the new features. boundary options (e.g. Add External, Add Material) to Multi-Scenario Modeling superimpose different slope geometries (e.g. back a slope). One of the major new modeling features introduced in Slide version 7.0 is Multi Scenario modeling. This allows The soil profile can be defined in several ways, including you to create, edit, and analyze multiple variations of a from the input of borehole data.

Tensile Strength Option With the new Tensile Strength option, the user does not have to manually define a tension crack. After defining a tensile strength cutoff, the tension crack depth is automatically found. In Tutorial 29 the is first carried out without using the new tension option. The effect of a tension crack is then examined. The tension crack is added manually in one file, and Choice of Single or Multiple Scenario in the Project Settings dialog. automatically in another through and moment equilibrium are satisfied.

The Release of Slide 7.0 2 RocNews Winter 2015 models using the load transfer curve method or better known as the p-y method for laterally loaded piles and the t-z method for axially loaded piles. The soil load transfer curves capture the non-linear soil- pile behavior by relating the soil reaction forces to the soil displacement at each depth. Various recommended load transfer curves are available in RSPile and are presented in the RSPile theory manual. For axially loaded piles, the load transfer curves are known as t-z curves for soil skin , and q-z curves for soil end bearing resistance. For laterally loaded piles, the load transfer curves are known as p-y curves for soil lateral resistance. You can read more about RSPile in RocNews Winter 2015 RSPile article.
