Landslide
Studies and Stabilization Measures
Landslides
can wreak havoc in many areas throughout
California. CGI Technical Services’s professionals have
extensive experience performing landslide
evaluations to estimate stability and methods
to stabilize failures. We offer the following
services: |
-
Landslide mapping
- Evaluation of landslide surface and subsurface geometry
- Estimation of critical soil and groundwater properties within landslides
- Geomorphic mapping of mass wasting features
- Instrumentation and monitoring of slopes
- Stability analyses
- Dynamic slope deformation
evaluations
- Numerical modeling of static and dynamic landslide conditions
- Rockfall and catchment evaluations
- Debris flow evaluation and
mitigation
- Evaluations of alternative stabilization measures
- Evaluations of alternative
methods of groundwater control
- Laboratory testing of soil
and rock strength parameters
- Construction observation
and testing during remediation
- Construction observation
and inspection ofdewatering
measures
- Forensic evaluations of
prior slope stabilization measures

CGI Technical Services’s
professionals have studied and stabilized landslides
throughout California and in southern Oregon. Those
landslides have included small features covering
a fraction of an acre to very large failures covering
tens of acres and more than 3-million cubic yards
of material. |
CGI Technical Services
utilizes a wide variety of methods
to evaluate landslides, including:
- Downhole logging
- Inclinometers
- Piezometers
- Extensometers
- Time Domain Reflectometry
- Fixed prisms
- Historical aerial photograph interpretation
- Detailed geologic mapping
- A wide variety of drilling methods
- Test pits and trenches |
