Title: Study Of Seepage And Stability Of Rural Dams Compacted In Three Different Moisture Contents
Author: Paschoalin Filho J.A.
De Carvalho D.
Abstract: This paper presents the study of stability and percolation of two dams sections with 5 m high, one composed by horizontal sand filter, and the other by a rockfill drain localized at the toe of the downstream slope. The stability analyzes were performed using Slope / W software, using the Simplified Bishop Method (1955), while the percolation analyses were performed by Seep / W software based on the theory of finite elements. In order to obtain the necessary parameters were conducted laboratory tests using disturbed and undisturbed soil samples collected at the Faculty of Agricultural Engineering at Unicamp. The samples used for shear strength determination and permeability tests were compacted at optimum moisture content and in 4% moisture deviation from this value in order to verify the influence of compaction moisture content on variation of slopes safety factors. The performed stability analyses demonstrated the variation of the safety factors depending of compaction moisture content, geometrical characteristics and type of drainage element. It was also observed that the flow in the analyzed sections occurs predominantly in foundation.
