Bir derin kazı işleminin komşu parsellerdeki alt ve üst yapı unsurlarında veya arsalarda herhangi bir stabilite kaybına ve yapısal hasarlara neden olmaması, inşaat işçi sağlığı ve güvenliği riski yaratmaması için önlemleriyle birlikte projelendirilmesi ve uygulanması gerekmektedir. Bu çalışma, temel kazısı nedeniyle oluşabilecek zemin hasarlarının bir örneğini temsil etmektedir. Kazı ile etkilenen zeminin özellikleri jeolojik araştırma yoluyla analiz edilmiştir ve farklı analiz aşamalar için zemin modelleri oluşturulmuştur. Çalışma, yaygın olarak kullanılan limit denge (LE) yöntemleriyle temel kazısında meydana gelebilecek şev stabilitesi analizlerini ele almaktadır. Bu makalede İstanbul Sarıyer ilçesi İstinye Mahallesi'ndeki 3 katlı bir okul binasının bodrum katının inşasından önce kazı çevresinde meydana gelebilecek şev problemleri incelenmiştir. Bölgeye ait detaylı sondaj raporları alınarak geoteknik ve yapısal parametreler belirlenmiş, çalışma alanı limit denge yöntemine dayalı Rocscience Slide 6.0 programı ile modellenerek bodrum kazıları değerlendirme sonucunda kazı sonrası bodrum inşası güvenliği için şevli kazı yapılmıştır ve şevli kazıların stabilite analizi sonucu eğim güvenliğinin yeterli olduğu tespit edilmiştir.

A deep excavation should be designed and implemented together with the precautions to prevent any loss of stability and structural damage in the infrastructure and superstructure elements of the neighboring parcels and risks against construction worker's health and safety. This study represents an example of soil damage that may occur due to foundation excavation. The features of the soil affected by the excavation were analyzed through a geological survey and soil models were created for each analysis stages. The study investigates the slope stability analyses that take place during the foundation excavation with the commonly used limit equilibrium (LE) methods. In this article, slope problems that may occur around the excavation before the construction of the basement of a 3-storey school building in Istinye Neighborhood of Istanbul Sarıyer district are examined. First, geotechnical and structural parameters were determined by obtaining detailed drilling reports of the region. Then the study area was modeled with the Rocscience Slide 6.0 program based on the limit equilibrium method. Following the evaluation of the basement excavations, a beveled excavation was made for the safety of the basement construction after the excavation and the stability of the slope excavations was found to be sufficient.
