Özet

This paper presents the effects of waste tires, water content, and relative density on the soil dominant frequency based on experiment. Cylindrical molds with a diameter of 30 cm and height of 50 cm are prepared to understand the effects of these materials. The molds are filled with sand at different relative densities (60% and 80%). In addition, samples are prepared by adding waste tire particles at different rates (0%, 0.5%, 1%, and 2%) to the sand to achieve different relative densities and water contents (0%, 5%, 10%, and 15%). The soil dominant frequency and horizontal/vertical (H/V) amplitude are determined using the microtremor technique by measuring each cylinder for 60 min using a broadband seismometer. Microtremor data are analyzed using the H/V spectral ratio (Nakamura) method. The experimental result shows that the waste tire particles added to the sand decrease the H/V amplitude. The most suitable environment features a relative density of 60%, which is achieved using 1% waste tires and 0% water content. Meanwhile, the most suitable environment has been achieved using 0% water content and 0.5% waste tire ratio for 80% relative density. Using the prepared composite material with waste tires as an additive on the soil may reduce the destructive effects of earthquakes.
