| Summary: | Field measurements of residual soil slopes are valuable for the assessment of slope stability
during rainfall. Several residual soil slopes, which are predominantly unsaturated due to their deep
groundwater table, were instrumented with tensiometer and rainfall gauge in order to study the response
characteristics of the slopes during rainfall. Comprehensive field measurement results involving a large
number of rainfall events are presented in the paper. The results show that the pore-water pressures in all
instrumented slopes increased in a similar fashion during rainfall, but at different magnitudes depending on
soil type. The pore-water pressure response characteristics can then be used to estimate the variation in factor
of safety of the slope during rainfall. |
