Abstract

ABSTRACT Banjir Kanal Timur Bridge, located in Semarang between Tanjung Mas Harbour and Kaligawe road, is built on soft soil. The bridge is supported by foundation piles, which did not reached hard soil layer, therefore it is very sensitive to the lateral forces or horizontal forces, may be caused by construction a new road or bridge close to it. For that reason, the research is needed to anticipate the existing bridge stability disturbance due to the new bridge construction. The research is carried out which in four location points surrounding the area of Banjir Kanal Timur Bridge Pier (1, 2, 3 and 4) covers soil test in the field and laboratory test. The result of soil test show that the soil in this area at deepth of – 0.00 m up to – 14.00 m is very soft clay to soft clay, while at depth of – 14.00 m up to – 23.00 m represents soft to firmness clay, the critical thickness embankment Hcr without load is 2.30 m with slip length (L) = 17.12 m and Hcr with load is 1.90 m with slip length (L) = 16.60 m with Factor of Safety (FS) = 1.2. It is conclude that the construction of new bridge would not disturb the stability of the existing bridge when built at least 17.12 m away from the existing bridge, and the embankment is need high than 1.90 m.
