Original paper


The Botan Bridge in Siirt (Turkey), now under construction, will carry a road across the River Botan and the lake which will be created by the Pervari Dam, 180 m high. The bridge has two piers with height of 115.88 m, and the total length of deck is 450 m which is built in accordance with the free cantilever method. The paper deals with foundations used in Botan Bridge for dam reservoir crossing bridge structures. Some of the geotechnical problems of construction of these foundations are highlighted. The slope debris deposits and basement rocks being ophiolite and the metamorphic rocks (calc schist, chlorite schist and meta-sediments) contribute to the geotechnical problems. Ophiolite, calc schist and chlorite schist, contains significant percentage of chlorite, feldspars, carbonates and serpentinites; their effect needs to be assessed in the interpretation of pier foundation construction and slope stability calculations. For this purpose, in situ and laboratory tests have been performed. Ophiolitic rock mass properties are an important factor for slope stability of rocks and foundation construction.
