This document addresses the environmental aspects that should be considered when undertaking a project. engineering qualities, such as low shear strength, high compressibility, undesirable permeability, or other characteristics, that could interfere with compaction operations and/or provide a poor surface for a struc-ture foundation. In tunnels laid on erosive soil deposits, pore water pressure build up due to traffic loading and ensuing seepage flow loosens soil particles beneath the tunnel invert, and mud slurry is pumped out from invert weep holes with a passing train load. conclusions included: (1) pumping requires three conditions, a subgrade … High-speed train travel round the world has given rise to newer geotechnical problems that require ingenious solutions. Clearing and grubbing entails removal of trees, brush, large roots, and other woody growth to expose the soil prior to earthwork operations. It reduces the thickness of concrete slab and thus leads to lower cost of construction. These are the failures in rigid pavements that is caused due to pumping in excessive rate.
