Earthquake Engineering Application and Research Center within Bursa Technical University continues its work to create "earthquake-resistant cities". Academicians from BTÜ, who have produced many projects to heal the wounds and conduct soil and structure risk analysis in the Kahramanmaraş-centered earthquakes that occurred on February 6, are also carrying out studies to increase Bursa's earthquake resistance. In this context, the work on preparing the Ground Liquefaction Map of Bursa together with the Metropolitan Municipality has started in Yıldırım and Osmangazi districts. With the resulting map, the risk of Bursa in terms of liquefaction will be revealed. In addition, BTÜ academics also provide technical support to the rapid superstructure scanning studies carried out by the Metropolitan Municipality in Yıldırım, Osmangazi and Nilüfer districts. Additionally, Associate Professor of the Department of Civil Engineering. Dr. It is planned to prevent soil liquefaction with the boron-added soil injection material developed by Eyübhan Avcı.
ALLUVY GROUND RISK IN BURSA
Noting that there are problematic areas in Bursa in terms of soil, Eyübhan Avcı noted that especially the areas where the Bursa plain passes through Nilüfer, Osmangazi and Yıldırım districts and the coastal parts of Gemlik and Mudanya districts consist of alluvial soils. Avcı said, “It seems that there is a risk of ground liquefaction in these areas and there are areas with soft ground characteristics. Especially in these areas, it is thought that the damage will be great in earthquakes of magnitude 6 and above. There is a great risk of damage in buildings built before 1999, those that sit on alluvial ground and those that have not been improved. There are risky areas in terms of landslides in Yıldırım, Osmangazi, İnegöl, Mudanya and Gemlik districts. "There is also the potential to trigger landslide formation in a possible earthquake," he said.
IMPLEMENTATION AGAINST LIQUEFACTION STARTS IN GEMLİK
Noting that the internationally patented boron-added ground injection material to prevent ground liquefaction will begin to be applied in Kurşunlu in a short time, Avcı said, “It is planned to prevent ground liquefaction with boron-added ground injection material. In this context, we are starting the first applications in Gemlik with the protocol we signed with Bursa Metropolitan Municipality. Currently, drilling has been completed within the scope of field work in the Kurşunlu coastal area, and the transfer of injection material and equipment to the field continues. "The developed material is aimed to be applied throughout our country," he said.
RISKY AREAS WILL BE DETERMINED BY MAP
Stating that detailed ground maps are planned to be prepared for the whole of Bursa in the following stages, Avcı said: “In the maps prepared, liquefaction zones, regions with soft soil characteristics, and areas at risk for landslides will be determined. In this way, areas that need intervention in terms of earthquakes will be determined and precautions that can be taken will be evaluated. “This study to be carried out is also very important in terms of determining reserve areas and urban transformation.”
LIQUEFACTION MAP OF İSKENDERUN FROM BTÜ
BTÜ academics, who carried out studies in Kahramanmaraş and İskenderun after the February 6 earthquakes, prepared ground liquefaction maps of Hatay's İskenderun district. Conducted by Assoc. Prof. Dr. This study by Eyübhan Avcı was supported within the scope of TÜBİTAK 1002C project. Detailed ground surveys were also carried out in the center of Kahramanmaraş, one of the regions where the most destruction occurred. As a result of these analyses, it was determined that some regions had a ground enlargement effect. Ground improvement solutions have been developed to reduce the effect of ground enlargement in new constructions.
Landslide Risk is Being Investigated in Kahramanmaraş
Detailed ground investigations continue in the Kahramanmaraş Boğaziçi region. Using field and laboratory test results, slope stability analyzes will be carried out and the landslide risk of the field will be evaluated. If it is determined that the area has a landslide risk, improvement methods that can be taken to prevent landslides will be determined.
BTÜ is always on the field for earthquakes
BTÜ Rector Prof. noted that BTÜ carried out many projects and studies before and after the earthquake. Dr. Naci Çağlar said, “We started our field work in the region from the first day of the February 6 earthquakes and we are still continuing. We contribute to the safe reconstruction of the region with the maps we create. Our cooperation continues in Bursa, which is at risk for earthquakes. We signed a protocol with Bursa Metropolitan Municipality for the application of our patented material that we developed against ground liquefaction. Our university is conducting research on the seismicity of Bursa together with the Japan International Cooperation Agency and Bursa Metropolitan Municipality. "Our academics take part in relevant commissions and carry out studies that will make a difference in this regard," he said.
