): The uniaxial compressive strength of the unjointed, intact rock pieces (measured in MPa or psi).
: You can check the Program Downloads page on the official Rocscience website. They typically provide an automatic update feature or full install links for free tools. Primary Function: Rock mass strength analysis
There are no complex menus. Everything from inputs to output plots happens on a single, easy-to-read screen.
RocLab addresses a key challenge in numerical modeling: obtaining reliable input data for complex programs. By converting rock classification data into robust parameters, it bridges the gap between geological field data and advanced engineering analysis. It is particularly useful for defining the mechanical behavior of rock when designing support systems like shotcrete and rockbolts.
