Landslide Mitigation

 

 

NGS conducts extensive slope stability analyses to arrive at safe solutions. The engineering parameters and the strata behavior encountered, is studied and necessary conclusions are drawn. The design parameters thus established based on this rigorous analyses form the input for the detailed slope stability analyses. The choice of the mitigation measure is based on the strata, the structure to be constructed and other suitability factors.
Some of the recent edeavours include:

 

• Excavation for Multi-storeyed RCC Structure at Mahim, Maharashtra. The challenges included proximity to Arabian Sea, tidal fluctuations, less clear space being available from the property-line boundary and the strata observed was not suitable for standing vertical without protection measure. Innovative and highly cost-effective solution using soil nails vs. conventional method resulted in timely and safe excavation being met.
  

 

• Landslide at Pune-Mumbai Expressway. The entire infrastructure saw many failures due to rock toppling. Also seepage zones being created in tunnel. The successful implementation of the recommendations at the assigned areas resulted in many appreciations for Dr. Kulkarni in the Newspapers.

 

• Deep cut at Indore, Madhya Pradesh. Mitigation measure for 52m deep cut was recommended.
  

 

• Portal Stability for Mahur-Maibong, Assam. The tunnel was proposed for this section. The strata included shale rock. The swelling problems associated with the shale are quite well known. Safe excavation procedures recommended resulted in successful completion of the challenging project.
  

 

• Middle Vaitarna Dam, Maharashtra. It would be the tallest dam in Maharashtra after construction. The severe landslide near the dam caused the culvert to move by 4m. The mitigation measures using Geo-jute and Soil nails have been recommended.
