Title: CONSTRUCTION PROBLEMS EXPERIENCED WITH LOESS SOILS
Accession Number: 00231306
Record Type: Component
Abstract: THE PHYSICAL PROPERTIES AND STRUCTURAL MAKEUP OF LOESS SOILS ARE BRIEFLY DESCRIBED, PRINCIPALLY WITH REFERENCE TO THE MANNER IN WHICH THEY CONTRIBUTE TO THE BEHAVIOR OF LOESS IN VARIOUS TYPES OF CONSTRUCTION WORK. THE INTERNAL STRUCTURE, STRATIFICATION AND SLOPE FACE PROBLEMS ARE DISCUSSED. CONSTRUCTION PROBLEMS OF LOESS IN THE CENTRAL NEBRASKA PROJECT ARE DESCRIBED. THIS PROJECT REPRESENTED A FAIRLY LARGE-SCALE PROJECT AND DEMONSTRATED THAT LOESS SOIL COULD SAFELY BE USED IN CONSTRUCTION WORK AS AN EMBANKMENT MATERIAL OR IN SITU AS A FOUNDATION MATERIAL FOR EARTH DAM STRUCTURES OR HYDRAULIC STRUCTURES. THE POLICY OF COMPACTING THE SOIL IN ALL DAMS WET OF OPTIMUM IS BELIEVED TO BE THE PRINCIPAL REASON THAT ALL STRUCTURES SAFELY WITHSTOOD THE RATHER SEVERE DIFFERENTIAL SETTLEMENTS THAT OCCURRED. THE SATISFACTORY BEHAVIOR OF THE STEEP BACK SLOPES USED ALONG THE POWER CANAL TO DATE (APPROXIMATELY 30 YEARS) IS AMPLE EVIDENCE THAT STEEP SLOPES SHOULD BE USED IN LOESS SOILS.
