| Summary: | A study on determining the stability of weathered rock cut slope using
geological mapping and laboratory tests. The study is divided into two parts: field
work and laboratory testing. The field study focused on the measurement and
analysis of the orientation and characteristics of discontinuity. Identification of
rock types, weathering grades and observation of cut slope conditions were also
included in the field study. Laboratory testing involved determination of natural
moisture content, particle size distribution and shear strength. Discontinuity data
were analyzed using stereographical method for identification of potential
instabilities. A factor of safety (FOS) analysis was conducted on unstable cut
slopes using SWEDGE software and manual calculation It is found that the
geological mapping and laboratory tests are feasible for assessing slope stability.
The FOS analysis has distinguished 10 slope to be considered as fail whilst the
other 6 are consider stable same as field observation. |
