Abstract

Antalya city centre is built on travertine rocks. In these travertines, which have karstic vugs, may sometimes have bearing capacity problems. In this study physical and mechanical properties of these travertines are investigated with laboratory experiments. Physical properties of Massif, plant tissued and vugged travertines were established with routine laboratory experiments which were taken on site from drilling core samples. Mechanical properties of these travertines were studied in three different situations. These were natural condition, kept in seawater for 90 days, and kept in wastewater for 90 days. These samples were tested with uniaxial pressure test device to determine its strength in these conditions. For this experiment, 3 core samples which were taken from the same types of travertines, were with respect to their strengths. The strength values of natural condition travertines were found between 3.5 MPa and 77 MPa. It was found that massif travertines have nearly 4 times more strength than plant tissued and 8 times more strength than vugged travertines. Also it is found that the strength of core samples which were kept waited seawater and wastewater for 90 days have less strength than natural condition travertines. Therefore it was observed that seawater and wastewater affects negatively the strength of travertines. Modulus of elasticity of natural condition travertines changes between 5 000 similar to 15 000 MPa, and this loses value of on average between %10 similar to %15 because of seawater and wastewater.
