Title:

COMPUTER SOLUTION OF SWEDISH SLIP CIRCLE ANALYSIS FOR EMBANKMENT FOUNDATION STABILITY

Accession Number:

00235382

Record Type:

Component

Abstract:

PERSONNEL OF THE MATERIALS LABORATORY AND OF THE COMPUTER SECTION OF THE WASHINGTON DEPARTMENT OF HIGHWAYS HAVE DEVELOPED A PROGRAM FOR THE IBM 650 MAGNETIC DRUM DATA PROCESSING MACHINE WHICH WILL ANALYZE A GIVEN FOUNDATION PROBLEM IN A MATTER OF MINUTES. AT PRESENT THE PROGRAM WILL HANDLE ANALYSES OF EMBANKMENT STABILITY WHERE THE FOUNDATION IS COMPOSED OF AS MANY AS 3 LAYERS OR STRATA OF DIFFERENT MATERIAL. ALTHOUGH THE PRESENT PROGRAM IS RESTRICTED TO HOMOGENEOUS EMBANKMENTS, SUITABLE MODIFICATIONS SHOULD ENABLE IT TO HANDLE ANY NUMBER OF EMBANKMENT OR FOUNDATION MATERIALS IF THEY ARE PLACED OR OCCUR IN A KNOWN GEOMETRIC PATTERN IN THE CROSS-SECTION. THE FOLLOWING DATA ARE NECESSARY FOR THE MACHINE ANALYSIS: COHESION, ANGLE OF INTERNAL FRICTION, AND UNIT WEIGHT OF THE SOILS INVOLVED, INITIAL SLOPE TO BE ANALYZED, THICKNESS OF THE FOUNDATION SOIL STRATA, HEIGHT OF EMBANKMENT, AND DESIGN SAFETY FACTOR. THE PROGRAM MAY BE USED IN TWO WAYS: (1) TO INVESTIGATE A GIVEN RANGE OF SLOPES, AUTOMATICALLY ADVANCING TO THE NEXT FLATTER SLOPE IF THE SAFETY FACTOR AGAINST FAILURE IS FOUND TO BE LESS THAN THE PREDETERMINED VALUE, AND (2) TO INVESTIGATE A RANGE OF SLOPES, IN INDIVIDUAL ANALYSES FOR EACH SLOPE. /AUTHOR/
