Abstract

Dams with high construction costs are subject to deformation due to internal and external factors, such as self-weight, temperature changes, the force of the reservoir water. The effects of these factors on structural behavior should be monitored and, if necessary, precautions must be taken. To serve the purpose of their establishment in a beneficial way, dams should be monitored periodically by geodetic or geotechnical methods. In this study, the studies on dam deformation monitoring with geodetic methods in the world and in Turkey were evaluated. Within the scope of the study, robotic total station and GNSS, terrestrial laser scanner samples were given. The aim of this study is to provide a summary of the current solutions and future tendencies to the people working on the investigation of the deformations in the dams by geodetic methods.

BARAJLARIN JEODEZİK YÖNTEMLER İLE İZLENMESİ ÜZERİNE YAPILAN ÇALIŞMALARIN İRDELENMESİ

Abstract

Yapım maliyeti oldukça yüksek olan barajlar, barajın kendi ağırlığı, sıcaklık değişimi ve su yükü gibi iç ve dış faktörlerden dolayı deformasyona maruz kalırlar. Bahsi geçen faktörler karşısında yapısal davranışın ne kadar etkilendiği izlenmeli, varsa hareketlerin belirlenmesi ve barajların güvenlikleri sağlanmalıdır. Barajlar kurulum amaçlarına sağlıklı bir şekilde hizmet etmeleri barajlar jeodezik ve geoteknik yöntemler ile izlenmelidir. Bu çalışmada, baraj deformasyonlarının jeodezik yöntemlerle izlenmesi konusunda Dünyada ve Türkiye’de yapılan çalışmalar değerlendirilmiştir. Çalışma kapsamında, jeodezik ölçüm tekniklerden robotik total station ve GNSS, yersel lazer tarayıcı örnekleri verilmiştir. Bu çalışmanın amacı barajlarda deformasyonların jeodezik yöntemler ile incelenmesi üzerine çalışan kişilere mevcut çözümleri ve gelecekteki yönelimleri anlamalarını özetleyerek sağlamaktır.
