Itasca has provided analysis of nearly all types of retaining structures, including slurry-supported reinforced concrete diaphragm walls, sheet pile walls, soil-nailed walls, and tieback walls. As with dams, water pressure acting within the soil mass is often a key issue. The ability to predict water pressures is an important element in understanding the behavior of retaining structures. Itasca ...

Itasca performs analyses for concrete/masonry dams (including arch, gravity, RCR - roller compacted concrete) and embankment dams (earth, rockfill, and mine tailings dams), including: Short- and long-term mechanical behavior analysis of dams on fractured rock. Optimizing dam design based on criteria constraints. Analyzing thermo-hydro-mechanical behavior of a concrete dam subjected to thermal ...

Microseismic monitoring allows for the imaging and visualization of active fracture networks within developing and producing EGS. Real-time monitoring of microseismic data can provide instant feedback on injection pathways in a treated field and potential fault rupture and propagation that can affect production efficiency. Post-processing offers a greater understanding of long-term reservoir ...

Natural barriers, including geological formations — salt, argillite, sedimentary or crystalline settings — constitute the most important component of the complex multilayered system that isolates stored waste from the biosphere. Therefore, the design and performance assessment of waste repositories require a thorough knowledge and understanding of host rock behavior. Itasca has ...

Combining experience, conventional approaches, and numerical modeling tools, Itasca can simulate mining of client’s sites first, to select mining methods appropriate to the orebody geometry, rock mass strength conditions, and stress state. Itasca understands the economics involved in any mine design and ensures that mineral recovery is optimized while satisfying subsidence criteria and ...

Itasca has developed unique and robust approaches to pillar design that recognizes the importance of understanding the rock behavior from intact rock and bedding to joints and faults. Itasca’s software can model the stress-strain response of continuous, blocky, or bedded materials exhibiting plastic, brittle, or creep behaviors. Consequently, any combination of lithology comprising the ...

Surface subsidence (vertical deformations) or mining-induced ground deformations (horizontal and vertical) are often an inevitable consequence of many mining methods. Itasca evaluates mining-induced subsidence related to the extraction of ore from both underground and open pit mines, together with dewatering-induced subsidence. Services provided include: field investigation for acquiring ...

Itasca designs the ground support layout and specification necessary to reinforce, retain, and hold the rock mass around excavations. The required level of ground support can be determined from an understanding of the rock mass strength, the initial (in-situ) stresses, and the stresses (magnitude and orientation) likely to change over time. By considering the evolution in induced stress over ...

Ground-structure-interaction is the iterative effect that ground deformations have on any emplaced stabilizing structures (beams, sheet pile walls, piles, liners, anchors, etc.), and vice versa. This is particularly important for heavy structures resting on relatively soft soils (Wolf, 1985). While limit equilibrium (LE) doesn’t capture ground-structure-interaction fully, Itasca’s ...
