from Wikipedia, the free encyclopedia

Philip C. Rutledge ( February 17, 1906 , † July 14, 1990 ) was an American civil engineer ( geotechnical engineering ).

Rutledge graduated from Harvard University ( bachelor's degree in 1927), earned his master's degree in civil engineering from the Massachusetts Institute of Technology in 1933, and received his PhD from Harvard in 1939. At that time he was one of the founders and pioneers of soil mechanics in the USA and organized the First International Conference on Soil Mechanics and Foundation Engineering (ICSMFE) at Harvard in 1937 with Arthur Casagrande . 1937 to 1943 he was a professor at Purdue University and then until 1952 at Northwestern University . There he developed new laboratory devices for soil mechanics with Jorj O. Osterberg . He also wrote an influential report on the shear strength tests of clay by Arthur Casagrande and Donald Wood Taylor at the Waterways Experiment Station in 1947 . During the Second World War he was an advisor to the US military for the construction of runways and led the soil mechanical research. From 1952 he was a freelance geotechnical consulting engineer in the company Mueser Rutledge Consulting Engineers in New York City (with William H. Mueser). In 1977 he retired.

In addition to fundamental questions of soil mechanics (such as the influence of pre-loading on the shear strength of clays, stability of foundations in the event of lateral loading, load transfer in pile foundations, influence of the disturbance of samples on consolidation tests), he worked as a geotechnical consultant, among other things, with dam construction, hydraulic engineering, tunnel construction, Foundations. He was involved in several large dam projects in California, advised on the Plowshare Project of the Atomic Energy Commission (use of atomic bombs for earthworks), barriers for salt control in the San Francisco Bay, foundations for particle accelerators at Lawrence Berkeley National Laboratory , pumped storage plants in New York, the foundation of the rocket assembly building in Cape Kennedy, the foundation of nuclear power plants on the Savannah River , the foundation of the Texas Towers (radar platforms on oil rigs), the subway in Washington, DC and the foundation of congress buildings in Washington and he was at the Atlantic-Pacific Interoceanic Sea Level US Army Corps of Engineers Canal Study involved.

From 1962 to 1974 he was chairman of the dam construction advisory board of the California Department of Water Resources.

In 1968 Rutledge gave the Terzaghi Lecture . He was a member of the National Academy of Engineering (1968). In 1955 he was President of the New York Section of the ASCE and from 1958 to 1960 President of the ASCE. From 1947 to 1952 he was chairman of their geotechnical engineering division.
