Bearing Capacity FREE

Wed, 12 Sep 2012 18:17:04 +0000

The application gives a preliminary value of the ultimate and design bearing resistance of the spread foundations with different shapes: rectangular, square, circular and strip footings.
This is a handy tool for geotechnical engineers, civil engineers and architects, which are working on foundations in civil and housing construction. Data sets of several types of soil are included in the app.
This is a version with limited functionality, a version with extended functionality, like GPS support, Photo documentation and PDF report generation and distribution via Email and Clouds is available.

RMR Calc Free

Mon, 12 Nov 2012 21:24:32 +0000

The application called RMR calc returns the Rock Mass Rating (RMR) value and its classification based on Bieniawski (1993).

A full Version with email function and InSitu Elastic modulus of deformation Em [GPa] (Young's Modulus) is available here:
https://play.google.com/store/apps/details?id=es.terrasolum.rockmassratingcalc2

This system of rock mass classification is widely used in geomechanics and rock mechanics and allows to relate quality ratings to geomechanical parameters of the rock mass in excavations, foundations and tunnel support.

To classify a rock mass using the RMR system, the following six parameters are used:
1. Uniaxial compressive strength of rock material.
2. Rock Quality Designation (RQD).
3. Spacing of discontinuities.
4. Condition of discontinuities.
5. Groundwater conditions.
6. Orientation of discontinuities.

The parameters are inserted in an easy and intuitve way by using slide bars.
These ratings are added to give a value of RMR between 0 and 100.

Geotechnical engineers working with tunnels, slopes in rock and foundations will obtain a coarse indication about Friction Angle and Cohesion of the Rock Mass.

This is a geotechnical tool. The application gives a preliminary value of the ultimate and design bearing resistance of the spread foundations with different shapes: rectangular, square, circular and strip footings.

This is a handy tool for geotechnical engineers, civil engineers and architects, which are working on foundations in civil and housing construction. Data sets of several types of soil are included in the app.

The type of soil and the parameters can be indicated. Finally a Geotechnical report with all soil and foundation data can be generated. There are also options to include photos and GPS data.

RMR Calc

Sun, 18 Nov 2012 17:30:32 +0000

The application called RMR calc returns the Rock Mass Rating (RMR) value and its classification based on Bieniawski (1993) and allows the user to email the results.

This system of rock mass classification is widely used in geomechanics and rock mechanics and allows to relate quality ratings to geomechanical parameters of the rock mass in excavations, foundations and tunnel support.

To classify a rock mass using the RMR system, the following six parameters are used:
1. Uniaxial compressive strength of rock material.
2. Rock Quality Designation (RQD).
3. Spacing of discontinuities.
4. Condition of discontinuities.
5. Groundwater conditions.
6. Orientation of discontinuities.

The parameters are inserted in an easy and intuitve way by using slide bars.
These ratings are added to give a value of RMR between 0 and 100.

Geotechnical engineers working with tunnels, slopes in rock and foundations will obtain a coarse indication about the elasto-plastic parameters Friction Angle, Cohesion and InSitu Elastic modulus of deformation Em [GPa] (Young's Modulus) of the Rock Mass. Used in many types of calculations and analysis all through civil engineering.

The results can be sent by email (text or PDF).
