Abstract

Şev duraylılık analizi açık işletme
ve karayolu gibi birçok mühendislik işlemlerinin tasarımı için çok önemlidir. Şev
duraylılığı genellikle limit denge ve sayısal analizler ile kaya kütlesi
sınıflama sistemleri kullanılarak değerlendirilmektedir. Şev yüksekliği bu
yöntemlerin çoğunda girdi parametresi olarak kullanılmaktadır. LiDAR ve TLS
gibi ileri yöntemler pahalı ve zaman alıcıdır ve profesyonel kullanım
gerektirirler. Bu nedenle, araştırmacılar taşınabilirlikleri, ucuzlukları ve
hızlılıkları nedeniyle genellikle şev yüksekliğinin belirlenmesinde basit
yöntemlere ihtiyaç duyarlar. Bu çalışmada kaya şevlerinin yüksekliği şerit
metre, altimetre, lazer metre, klinometre ve jeolog pusulası ile
belirlenmiştir. Ölçümler dik (90̊)
 ve eğimli şevlerden (75̊) alınmıştır. Ayrıca, eğimli
şevlerde (45̊–90̊)
yöntemlerin mekanizmasını anlamak için laboratuvarda çeşitli modeller
geliştirilmiştir. Kullanılan yöntemlerin bulguları birbiriyle kıyaslanmış ve
yöntemlerin güvenilirliği tartışılmıştır. Yöntemlerin güçlü ve zayıf yanları
vurgulanmıştır. Bu çalışma bazı etkenlerin (ölçüm mesafesi, şev genişliği,
zeminin eğimi, şev topuğu önünde engebeli yüzey, vb.) şev yüksekliği
tahminlerini olumsuz etkilediğini göstermiştir.

A Comparative Analysis of Slope Height Using Simple Methods

Abstract

Analysis of
slope stability is crucial for the design of many engineering processes such as
open pit mine and highway. Slope stability is generally evaluated by limit
equilibrium and numerical analyses, and rock mass classification systems. The
slope height is used as the input parameter in many of these methods. Advanced
methods such as LiDAR and TLS are expensive and time consuming and they require
professional use. Therefore, researchers generally need to use simple methods
for the measurement of slope height because of their cheapness,
rapidity and portability. In this study, height of the rock slopes was
determined with tape line, laser meter, altimeter, clinometer and geological
compass. Measurements were taken from steep (90̊) and inclined slopes (75̊).
Further, various models were developed in the laboratory for understanding the
mechanism of methods in inclined slopes (45̊–90̊). The findings of methods used
compared with each other and the reliability of the methods was discussed. Strengths
and weakness of the methods were highlighted. This study indicated that some
factors (measurement distance, slope width, the inclination of the ground, rugged surface in toe of the slope, etc.) can
negatively affect the estimations of slope height.
