Effect of Dwarf Bamboo for Stability of a Slope Surface
Abstract:In order to study the effect of dwarf bamboo for the stability of a slope surface, a series of laboratory tests were conducted with an intensive field investigation on the slope slid by the earthquake. As a result of shear tests, it was considered that the effect by the rhizome of dwarf bamboo is quite similar to that of geotexti1e. Using the parameters obtained from the tension test of rhizome, the field investigation and the earthquake record, the slope stability was evaluated by the safety factor which was given as a function of tensile force of the rhizome per unit slope length. In this analysis, it was shown that the factors were less than 1.0 during the earthquake while they exceeded 1.2 under the static condition, so that the results supported the sliding slope.
