Abstract

In this study, an analysis of the deformations and the stability of tunnel face in soft soil using several calculation procedures aimed at making confrontations are presented. Our purposes to approach three-dimensional modelling in tunnelling by a series of 2D computations using three procedures: The Lost Volume method (LVM), the Convergence Confinement method (CCM) and the face pressure method (Pf). A series of numerical studies was carried out to estimate the settlements, longitudinal and horizontal displacements. Analytical and empirical approaches have also been used to make comparisons. The results showed the interest of such analysis. The comparison of the numerical results to those calculated with different methods shows good agreement.

Özet

Bu çalışmada, yüzleşmeler yapmayı amaçlayan çeşitli hesaplama prosedürleri kullanılarak yumuşak zeminde tünel yüzünün deformasyonlarının ve stabilitesinin bir analizi sunulmaktadır. Üç prosedür kullanarak bir dizi 2B hesaplamayla tünellemede üç boyutlu modellemeye yaklaşma amaçlarımız: Kayıp Hacim yöntemi (LVM), Yakınsama Sınırlandırma yöntemi (CCM) ve yüzey basıncı yöntemi (Pf). Oturmaları, boyuna ve yatay yer değiştirmeleri tahmin etmek için bir dizi sayısal çalışma yapılmıştır. Karşılaştırma yapmak için analitik ve ampirik yaklaşımlar da kullanılmıştır. Sonuçlar, böyle bir analizin ilgisini gösterdi. Sayısal sonuçların farklı yöntemlerle hesaplananlarla karşılaştırılması iyi bir uyum göstermektedir.
