Abstract

During the excavation of pump house-II of Kaleshwaram Lift Irrigation Scheme (KLIS) Link-II, sudden slope failure happened on the upstream wall from existing ground level +274.00 to +225.00 m level. In this paper the cause of slope failure at the upstream right-side wall of the pump house and support recommendations for the failure zone are discussed. 126 m long, 50 m wide (including annexure building) and 75.00 m deep, vertical shaft type pump house is being constructed for lifting the 361 cumecs water. Kinematic analysis was carried out to define the shape of the wedge, the orientation of the line of intersection and the direction of sliding. Equal angle projection was used for the analysis. Stability analysis was also done using the stability charts and Swedge RocScience software. The factor of safety (FOS) calculated using the stability chart is 0.44 and using Swedge is 0.4367. Mohr-Coulomb method of failure criterion is used for the analysis. After detailed analysis suitable engineering measures which include rock bolts, grouting and retaining RCC wall were recommended for the stabilization of the wedge portion of the upstream wall of the pump house and the same are being executed at the site.
