After the 1999 Marmara earthquake, serious damages occurred in some of the drinking water networks of Sakarya province, and almost all of the sewerage networks became inoperable. In this study, the vulnerability of buried pipes, which constitute a large part of the potable water supply and distribution networks of the infrastructure systems of Sakarya province, against seismic hazards were analyzed by the Hazard US (HAZUS) method. The maximum ground velocity used in the analysis of the vulnerability of buried pipes against possible earthquakes was determined with the help of classical probabilistic earthquake hazard analysis. Soil classes used in vulnerability analysis were calculated with the help of seismic data taken from 2044 points throughout the province. Sakarya province potable water pipe inventory was created and vulnerability parameters were defined for all pipes with the help of geographic information systems. The HAZUS method, which is frequently used in the literature, was used for pipe vulnerability analysis. As a result of the analysis, damage repair rates expressing the vulnerability of all pipes were obtained and the pipes were classified according to their damage repair rates.
1999 Marmara depremi sonrası Sakarya ili içme suyu şebekelerinin bir kısmında ciddi hasarlar oluşmuş, kanalizasyon şebekelerinin ise neredeyse tamamı hizmet veremez duruma gelmiştir. Bu çalışmada, Sakarya ili altyapı sistemlerinden içme suyu temin ve dağıtım şebekelerinin büyük bir bölümünü oluşturan gömülü boruların sismik tehlikeler karşısındaki hasar görebilirlikleri, Hazards US (HAZUS) metodu ile analiz edilmiştir. Gömülü boruların olası depremlere karşı hasar görebilirliklerinin analizinde kullanılan en büyük yer hızı, klasik olasılıksal deprem tehlike analizi yardımıyla belirlenmiştir. Hasar görebilirlik analizlerinde kullanılan zemin sınıfları, il genelinde 2044 adet noktadan alınan sismik veriler yardımıyla hesaplanmıştır. Sakarya ili içme suyu boru envanteri oluşturulup tüm borulara coğrafi bilgi sistemleri yardımıyla hasar görebilirlik parametreleri tanımlanmıştır. Analizler sonucunda tüm borular için hasar görebilirliği ifade eden hasar onarım oranları elde edilmiş ve borular hasar onarım oranlarına göre sınıflandırılmıştır.
