The Creep Response Of Cohesive Soils: A Method Of Design Using Rheological Strength Parameters, David L. Allen
The Creep Response Of Cohesive Soils: A Method Of Design Using Rheological Strength Parameters, David L. Allen
Kentucky Transportation Center Research Report
The creep response of four remolded soils and undisturbed soils from two landslide sites is presented. A method for obtaining the yield stress of soil from creep test data is presented and discussed. "Viscosity diagrams", showing the location of the yield stress is approximately 50 percent of peak stress, were obtained from conventional triaxial tests. There is more scatter in data from undisturbed soils than in data from remolded soils. Mohr's failure envelopes, constructed from yield stress data, give internal friction angles having values from approximately five to ten degrees. Strength data, calculated indirectly from peak relaxation modulus, are also …
Slope Stability Analysis: A Computerized Solution Of Bishop’S Simplified Method Of Slices, Steve M. Yoder, Tommy C. Hopkins
Slope Stability Analysis: A Computerized Solution Of Bishop’S Simplified Method Of Slices, Steve M. Yoder, Tommy C. Hopkins
Kentucky Transportation Center Research Report
A computer program based on Bishop's simplified method of slices (1954) and capable of analyzing the slope stability of a multilayered soil mass is described. The computer program was specifically developed for analyzing the slope stability of highway bridge approach embankments; however, it can be applied to a broad spectrum of practical slope configurations and bearing capacity problems. Details of the use, applications, and accuracy of the program are presented. Important features of the computer program include a grid type, search operation for locating the critical shear surface and a ledger printout of the forces acting on each individual slice. …
Settlement Of Highway Bridge Approaches And Embankment Foundations, Bluegrass Parkway Bridges Over Chaplin River, Tommy C. Hopkins
Settlement Of Highway Bridge Approaches And Embankment Foundations, Bluegrass Parkway Bridges Over Chaplin River, Tommy C. Hopkins
Kentucky Transportation Center Research Report
The report examines the cause of a differential settlement between the highway approach embankments and bridge decks and abutment tilting at a bridge site located on the Bluegrass Parkway in Kentucky. The site contains several design, construction and maintenance features and soil types that are typical of many bridge sites in Kentucky. The approach embankments are side-hill fills. The approach pavements have settled several inches and have been patched on numerous occasions. Each of the four abutments give the appearance of having tilted backward toward the backfill. However, closer examination shows that the abutments have moved laterally toward the bridge …
