DETERMINATION OF DEFORMATIONS OCCURED IN UNDERGROUND DRIFT BY TERRESTRIAL LASER SCANNER

Öz

Determination of the deformations evolved during the excavation is crucial for the economical and safe excavation. The applications of terrestrial laser scanning (TLS) technique in deformation monitoring is getting attention in recent years due to advantages of rapidity, high accuracy and applicability in large areas in a short time. On the other hand the studies involving the evaluation of the data gathering from terrestrial laser scanner for the deformation analysis is still up to date. In this study, deformation of an underground drift was determined by the aid of terrestrial laser scanner measurements. Three different methods; Cloud to cloud, cloud to mesh and cross-section analysis were carried out for the deformation analysis. Then the results of these methods were compared

YERSEL LAZER TARAYICI İLE YERALTI GALERİSİNDE MEYDANA GELEN DEFORMASYONLARIN BELİRLENMESİ

Öz

Yeraltı kazı çalışmaları esnasında meydana gelen deformasyonların en yüksek doğrulukla belirlenmesi kazı işleminin emniyeti ve ekonomisi için son derece önemlidir. Son yıllarda yersel lazer tarayıcıların yeraltı deformasyon ölçümlerindeki uygulamaları hızlı, yüksek doğrulukla ve büyük alanlarda kısa sürede veri elde edebilmesinden dolayı gittikçe önem kazanmıştır. Öte yandan yersel lazer tarayıcılar ile yeraltından elde edilen verilerin deformasyon amaçlı değerlendirilmesi konusu hala güncel bir çalışma alanıdır. Bu çalışma kapsamında da örnek bir yeraltı ocağından yersel lazer tarayıcı ile alınan ölçüm sonuçlarına göre deformasyon analizleri yapılmıştır. Deformasyon analizleri yapılırken nokta bulutu – nokta bulutu, nokta bulutu-model mesafesi ve kesit analizleri olmak üzere üç yöntem kullanılmış ve bu üç yöntemin sonuçları karşılaştırılmıştır
