This website includes selected publications by Philip Pells and Steven Pells that may be useful but are difficult to find elsewhere. These include guidelines that have been widely used in the design of earth dams, tunnels and foundations.
Philip’s period of study at Imperial College was very influential on his understanding of rock and soil mechanics. Some of his old lecture notes were discovered in the attic, and were scanned and posted here:
Effective Stress and Shear Strength of Soils – Alan Bishop
Earth and Rockfill Dams – Alan Bishop
Stability of Natural Slopes – Alec Skempton
