Geotechnical Instrumentation & Performance Monitoring

Deformation of soil involves the combined effect of elastic, plastic, and viscosity making its behavior rather complex. In addition to the complex nature of soil deformation, the additional stresses imposed on the soils are varied not only in terms of magnitude but also in the directions. This makes the prediction of deformation of soil to be extremely difficult. However, geotechnical engineers have been predicting ground behavior in advance with the help of finite difference or finite element computer modeling. Nevertheless in most cases performances were far from predictions due to the complexibility of the soil profile, parameters and hence loading conditions. Therefore geotechnical instrumentation fills the gap between prediction and performance and saves the soil mass failure as well as damages to the structure on the ground. Geotechnical instrumentation can provide construction control as well as performance monitoring. First one will provide safe construction of earth as infrastructure on the soil whereas the second one provides in-situ soil parameters from the back analysis, from which a more economical and safe design can be established.

DST has the capability to plan and install the following various types of geotechnical instruments as well as monitor and interpret the measured data to manage the risk of damages or deformation likely to be caused by the construction.
