Evaluation of the displacement of rock boulders subjected to dynamic forces, on the basis of a given accelerogram - determination, through pseudostatic analysis, of the acceleration that is necessary to bring the slope to limit equilibrium conditions - evaluation of the velocity and displacements in the direction of the sliding for each point of the considered accelerogram and calculation of the total displacement at the end of the seismic event in order to evaluate the stability of the slope under examination.
Foundation analysis and design - bearing capacity of shallow foundations with different shapes - comparison of the most used calculation methods - homogeneous and stratified soils - bearing capacity of deep foundations: micropiles, small and large diameter piles - immediate and long term settlement in homogeneous or stratified terrain for single and for multiple shallow foundations - differential settlement - verification under seismic conditions and in the presence of water
Classification of rock masses with the Bieniawski (RMR index) and Barton (Q index) methods - the results of the calculation are presented as a list that can be viewed and directly printed by the program or imported into any word processor.
Design and verification of sheet-piles and bulkheads - several levels of anchoring can be defined under different load conditions - iterative calculation for correct evaluation of successive excavation phases - the structure is calculated as a flexible beam on elasto-plastic supports with different constraints at the extremities - structural analysis of different sections (continuous diaphragms, beam bulkheads, armoured piles, sheet-piles) is performed through the determination of the moment and vertical stress, determined in the section under the highest stress, with a method based on the limit-state concept used in conjunction with the partial safety factor method (Eurocode 2).
Verification of the stability of slopes in granular soils - calculations under normal and seismic conditions - analysis of sliding surfaces with arbitrary shape or families of plane or circular sliding surfaces - analysis in the presence of water, in terms of total or effective stresses - possibility of dealing with heterogeneous stratified terrains - verification of the interaction between the slope and the restraint systems.
Interpretation of static and dynamic geotechnical in situ tests according to the most commonly adopted methods - STP tests: relative density, friction angle, effective and total vertical stress, constrained modulus, Young's modulus, cone resistance, shear modulus, cyclic modulus of deformation, upper limit allowed for the subsidence/load ratio. - CPT tests: friction angle, drained compressibility and relative density, undrained shear strenght, compressibility, sensitivity and overconsolidation - DP tests: all the information for the SPT tests is supplied - the program can be adapted to any measuring apparatus through correlation coefficients
Construction of map surfaces for geological sciences - contour lines - perspective views - the calculation methods are: inverse distance weighting, kriging, extrapolation of the surface with the recognition of the regional polynomial trend trough the elimination of closures of the contour lines - vectors and flow lines - digital filtering for geophysical techniques
Determination of the safety factor for the liquefaction of saturated coehsionless soils subjected to seismic tremors - the evaluation of soil resistance to cyclic shear forces is determined through the correlation between the resistance to liquefaction and the number of blows of the STP test - it is also possible to consider the presence of overloads and the water table effect - the resistance to liquefaction factor is calculated as the ratio between of the shear force that induces liquefaction and the maximum shear force induced by the seismic waves.
Analysis of rock slope faces with the Key Block Theory - recognition of the main discontinuity sets through hierarchical and non-hierarchical clustering - analysis of real discontinuities, based on their length and position on the slope face - identification of complex removable blocks based on the selected kinematic mode - determination of the volume of the rock blocks and of the safety factor of each identified block - design of the rock bolting that is necessary to reach a required safety factor.
Three-dimensional analysis of rockfalls - determination of the path of falling boulders - frequency distiribution contour lines of the stop points of the rock blocks - energy distribution in relation to the mean and maximum kinetic energy - planimetric graphical restitution and in-section restitution of resulting data - optimisation of protective systems.
Verification and design of retaining walls - gravity, semigravity and cantilever retaining walls - evaluation of the safety factor under normal and seismic conditions - validation of the concrete design and dimensioning of the reinforcement through the calculation of the bending moment of the foundation and of the footing pressure.
