(0 customer reviews)

Software for determining the failure criterion of a rock mass according to the model of Hoek-Brown (2002).

The software also calculates the strength parameters of the rock mass and allows for the calculation of the bearing capacity of foundations on rock according to the methods of Carter – Kulhawy, Serrano – Olalla – Gonzales.

Description

HOEK – BROWN FAILURE CRITERION

Using a linear approximation of the curvilinear envelope failure criterion of Hoek-Brown, in a range of stress fields, one can obtain the cohesion and angle of shearing resistance parameters of Mohr-Coulomb.

DATA REQUIRED

Compressive strength of the intact rock, GSI (Geological Strength Index), specific rock mass parameters, disturbance factor, and deformation modulus.

Some of the parameters, such as GSI, and own parameters, are identified directly by the software through interactive graphical procedures.

CALCULATED DATA

Constants of the rock mass s e a, tensile strength, the upper limit of confinement stress relative tunnels and slopes, global rock mass strength, cohesion and angle of shearing resistance.

Calculation parameters and design parameters distinguish the geotechnical parameters calculated.

CALCULATION OF PARAMETERS FROM TRIAXIAL TESTS

Through laboratory tests, like triaxial tests, performed with Hoek and Brown cells, in which the peak failure strength is measured with the variation of confinement stress, it is possible to calculate the rock’s resistance to compression and the parameter mi.

FOUNDATIONS BEARING CAPACITY

RockLab allows obtaining of geotechnical parameters according to the following design process.

The check for ultimate limits states of the soil-foundation complex concerns the failure mechanisms determined by the mobilization of global resistance of materials.

The ultimate bearing capacity of the rock mass is calculated using the methods of Carter-Kulhawy and Serrano-Olalla-Gonzales.

Using the ultimate bearing capacity is calculated the design resistance

RESULTS

Results are displayed both numerically and graphically.

The software produces a detailed calculation report.
