In general, combined effect of elastic, plastic, and viscosity parameters creates soils deformation. Thus, soils behavior becomes complex and hard to predict. Geotechnical engineers predict ground behavior using finite difference or finite element computer modeling. However, complexity of the soil profile and loading conditions in some cases makes the performance of the soils far from the predictions. Geotechnical instrumentation fills the gap between prediction and performance. It helps prevent soil mass failure as well as damages to structure on the ground. Geotechnical Instrumentation, on one hand, monitors structural and soils deformation, stresses on structural elements, and ground water pressure and inflows. On the other hand, it provides construction control and performance monitoring for safe construction.
Where limited geotechnical instrumentation may be used for simple projects; it is crucial for successful completion of critical and complex projects such as tunnels, slopes, deep excavations near sensitive structures, and so forth. In general, the process of applying geotechnical instrumentation to a project includes the following steps:
- Monitoring system design
- Procurement and supply
- Installation, commissioning, and testing
- Baseline readings
- Monitoring and data presentation
Geo-Advantec team has completed several unique instrumentation projects, some in Southern California. We are specialized in design, installation, monitoring, and data analysis of instrumentation projects.
