Assessment of the Rock Slopes by Kinematic and Limit Equilibrium Methods on the Bağlarbaşı - Tekke (Gümüşhane) Motorway

Abstract

Kinematic analysis method is one of the widely used methods to evaluate potential failures such as planar, wedge and toppling in rock slopes. In this method, orientations of slope and discontinuity with the friction angle of the discontinuities planes are used to analyze possible failure types. However, the reliability of the results obtained from kinematical analyses is not sufficient for optimum slope design. For this reason, it is necessary that the results of kinematical analyses should be controlled using limit equilibrium or numerical analyses. In this study, stability of rock slopes on the highway of Bağlarbaşı-Tekke (Gümüşhane) was investigated using kinematical and limit equilibrium analyses. The results of thekinematical analyses showed that there may be planar and wedge type instabilities for the rock slopes numbered 5, 6, and 7. The limit equilibrium analyses conducted for the types of plane and wedge show that the rock slopes numbered 5 and 6 are instable while number 7 is stable.

Bağlarbaşı-Tekke (Gümüşhane) Karayolundaki Kaya Şevlerinin Kinematik ve Limit Denge Yöntemleri İle Değerlendirilmesi

Abstract

Kinematik analiz yöntemi, kaya şevlerinde düzlemsel, kama ve devrilme gibi yenilmeleri değerlendirmek için yaygın olarak kullanılan analiz yöntemlerinden birisidir. Bu yöntemde, olası yenilme tiplerini belirlemek için şev ve süreksizliklerin yönelimleri ile süreksizliklerin içsel sürtünme açıları kullanılır. Ancak, kinematik analizlerden elde edilen sonuçların güvenirliği optimum şev tasarımı için yeterli değildir. Bu nedenle, kinematik analiz sonuçlarının limit denge analizleri veya sayısal analizler ile kontrol edilmesi gereklidir. Bu çalışmada, Bağlarbaşı-Tekke (Gümüşhane) karayolundaki kaya şevlerinin duraylılığı kinematik ve limit denge analizleri ile incelenmiştir. Kinematik analiz sonuçları, (5), (6) ve (7) nolu kaya şevlerinde düzlemsel ve kama tipi duraysızlıkların ortaya çıkabileceğini göstermektedir. Düzlemsel ve kama türü için yapılan limit denge analizleri, (5) ve (6) nolu şevlerin duraysız iken  (7) nolu şevin ise duraylı olduğunu göstermektedir.
