| Summary: | Mining world can not be separated from the geotechnical factors, in particular the
problem of slope stability. Therefore, a mining slope should always be monitored
and maintained during the mining operation. Slope stability is influenced by
several internal factors and external factors, one of them is vibration.
In this work, the test was conducted by using silty sand soil material with the
volume ratio of the sand and clay were 7: 3. The height of slope was 15 cm and
angle of slope was 30°. The concrete column’s material was consisted of a
mixture of sand and cement with the same volume ratio. The experiments were
conducted with centrifuge modeling technique to obtain critical acceleration of
slope to failure with several scenarios of concrete column reinforcement.
Based on the result of the tests, the critical acceleration of unsupported soil slope
was 0.67 g - 0.84 g. The results show that the critical acceleration of soil slope
presents an increasing trend with the increase in number of concrete columns, and
the volume of landslide presents a decreasing trend with the increase in number
of concrete columns applied on slope. |
