Abstract

It is important to perform research to the degree that it is adequate to identify the features of the terrain composition, before, during, and after the building of facilities since predicting the behaviour of rock mass during tunnel construction is a complicated engineering challenge. Engineering research works in laboratories and in the field are of different scope and methodology during testing. In this paper, the established interdependencies of some of the basic parameters obtained during the testing of rock mass are presented: Edyn = f(Vp), Edyn = f(RMR) i Edyn = f(Q). Also, the relations between the engineering systems of rock mass classification and seismic primary waves are derived. RMR = f(Vp), Q = f(Vp). The relations were based on the examination of the rock mass for the construction needs of the tunnel on the Nis-Merdare highway. The results obtained in this study can be applied in environments that have similar lithological and structural characteristics.
隧道施工中岩体初始参数的外推技术
由于预测隧道施工期间的岩体行为是一项复杂的工程挑战,因此进行足够的研究以确定设施建设之前,期间和之后的地形组成特征是很重要的。在实验室和现场进行的工程研究工作在测试过程中具有不同的范围和方法。本文给出了岩体试验中得到的基本参数Edyn = f(Vp)、Edyn = f(RMR)和Edyn = f(Q)之间已建立的相互关系。并推导了岩体分类工程系统与地震主波的关系。RMR = f(Vp), Q = f(Vp)这些关系是根据尼斯-默代尔高速公路隧道施工需要对岩体进行的检查而建立的。本研究结果可应用于具有相似岩性和构造特征的环境。
