. field. Moisture contents were also simulated to be as close to
the actual field conditi ons as possible. The results of the
tests indicated that the fine sandy silt alluvium material has a
minimum friction angle of approximately 32 degrees with a
cohesion of 0 psf, while the fine to medium grained sand has a
minimum friction angle of approximately 35 degrees with a
cohesion of 0 psf. These test results were then utilized in the
slope stability program to determine the overall safety factoc of
the slope. The result s of the triaxial shear tests are
summarized on Table 1.0. The actual plot of the test results
have not been completed at this time by Colorado State University
which performed the shea r tests. The plot of the shear tests
will be issued once they h ave been completed.
