Abstract

Two Hydro Power Houses are under construction on the Sutlej Yamuna Link Canal emanating from river Sutlej at Nangal in the State of Punjab, India. These Power Houses, one (2X18 MW) at Ropar and another (2X7.45Mw) at Rajpura had silty-clay soil strata with heterogeneous dispersion under the Power House. Further bearing capacity of the foundation was much lower than the impressed loads and settlements were heavy, while permissible tilt in the vertical shafts of the Hydro-generating machines is 3 mm in 10M height. So it was necessary to provide strengthening measures at both the sites. For Ropar Hydel Power House replacement of soil by river borne material i.e. gravel mixed with sand, upto 6 M depth below the raft has been done while in case of Rajpura Hydel Power House 0.45 M diameter 10.50 m deep granular piles spaced at 0.9 M staggered both ways have been provided.

Soil Strengthening of Sutlej-Yamuna Link Canal Power Houses in Punjab, India
