ABSTRACT

Because of very mountainous topography features in Korea, cutting slope tends to be generated during the construction of road, railroad and the building structure. A natural slope is usually on the top of cutting slope created during construction. As for evaluating the stability of cutting slope, the effect of a natural slope on slope stability has not yet much been studied. This study thus is intended to review the safety of natural slope on cutting slope that may vary depending on slope and analysis scope and then seeks the way of incorporating it into stability analysis. A stability analysis was conducted on a simple model assumption while adjusting the slope and analysis scope in a bid to evaluate the effect of natural slope pattern on slope stability. Consequently, a certain part of natural slope should be included to adequately estimate the safety level of cutting slope. This study suggests that at least 12m should be included for sandy soil slope in the scope of stability analysis, while 18m for cohesive soil slope.
