Conf. on Use of Fabrics in Geotechnics, Paris,'77 <br /> <br />"Water: Key Cause of Pavement Failure?", Co-authored <br />with Kneeland A. Godfrey, Jr., Editor, Civil Engin- <br />eering, ASCE, Sept. 1974, pp. 78-82. <br /> <br />(a) During employment period (1939-1967): <br /> <br />(1) Design of earth and earth-rock dams having <br />heights up to 300 ft, for wide range of soil and geo- <br />logical conditions. <br /> <br />(2) Design of pavements and subsurface drainage <br />systems for military roads and civil airfields in the <br />Pacific Northwest. <br /> <br />(3) Site examinations of numerous large highway <br />cut slopes in unstable terrain; recommendations for <br />stabilizing these slopes to prevent slides. <br /> <br />(4) Site examinations of numerous weak foundation <br />sites for highway fills and developm8nt of systems for <br />stabilizing and consolidating the mud and peat founda- <br />tions. Numerous mud foundations in the San Francisco <br />Bay area were involved. <br /> <br />(5) Seepage and Drainage problems of wide variety. <br /> <br />(6) Site examinations of numerous landslides with <br />recommendations for their treatment. <br /> <br />(7) Detailed studies of the strengths of weak mud <br />and other poor foundations for fills and various kinds <br />of structures. Development of concepts for evaluating <br />the strengths of weak foundations both before loading <br />and after being loaded by fills or other weight. <br /> <br />(b) During consulting period (1967-1977): <br /> <br />(1) Retained by Ebasco Services, New York, to study <br />seepage problems and drainage needs of Ludington Pumped <br />Storage Project and to develop drains for controlling <br />seepage. <br /> <br />(2) Retained by Ebasco Services, Atlanta, to study <br />seepage from ash storage ponds for steam electric <br />stations. <br /> <br />(3) Retained by U. S. Army Corps of Engineers, <br />(Alaska District, Portland District, Seattle District, <br />and Sacramento District), to study problems of design- <br />ing levee systems or dams with underseepage problems. <br /> <br />(4) Retained by Calif. Dept. of Water Resources to <br />analyze seepage mound developing below a major earth <br />dam. <br /> <br />-4- <br />
