Experimental and Analytical Study on the Strength of the Gutter’s Abutment

Abstract

Generally, JIS type gutter is used in road construction. However, in the case of backfill, there's a possibility that compaction is insufficient when it is using. Therefore a rectangular section gutter was developed by the authors to improve constrains of construction caused by JIS type gutter. However, the range of strength of its abutment varies in relation to the load position as the shape of abutment is corbel and the shape changes depending upon the size of each product. In this study, first, the strength and deformation behavior up to peak load of a test specimen was measured during experiments. Furthermore, 2-dimensional RBSM (Rigid Bodies Spring Model) analysis was carried out to simulate experiments and very similar results are obtained. After that, the strength of abutment (Size 250) of an actual size product was estimated by using 2-dimensional RBSM analysis.
