Slope Stability

Engineers and planners often face the challenges of Land Slides primarily in Hilly Terrains of Himalayas during the rainy season. ORIZON has developed a unique strategy for investigating such land slide zones for slope stability which can provide the key engineering properties of the soil / overburden (bed rock profile, overburden thickness, compactness of material etc.) for the appropriate management and monitoring of existing and potential landslides. Using the Geophysical Techniques, compressional and shear strength of the bed rock and overlying overburden together with their relative clay and water composition are determined. Poisson’s Ratio and a range of elastic moduli, i.e. Shear, Young’s and Bulk Mudulus can also be derived from the measured P and S-wave velocities and presented in desired cross-section which are used for interpreting the type of soil / rock and their strength. While each site is considered unique and specific approach and customized methodology is adopted for each site,

the most commonly used techniques by ORIZON for slope stability which prove to be most suitable are:

  • Seismic Refraction
  • Seismic Reflection
  • Resistivity Imaging / Tomography
  • Ground Penetrating Radar
