Abstract

Climate change is affecting rainfall patterns which in turn are having a demonstrable effect on slope stability.
This is a serious safety concern for EU rail networks. Accurately assessing slope stability is critical in maintaining a safe and
efficient railway infrastructure. Soil matric suction is naturally present in all soils which lie above the water table. Therefore, it
is a critical component in maintaining embankment stability. Rainfall infiltration causes a decrease in matric suction which
subsequently reduces the shear strength of the soil. This can be a triggering effect for many slope failures. This paper describes a
tensiometer based apparatus for measuring soil matric suction in a laboratory environment. It also outlines a method for
determining the minimum matric suction left during a heavy rainfall or flood event.
