Grouting of Rock Masses
The grouting of rock used to be a quite empirical constructional technique aimed to improve somewhat the physical properties of the masses, which are actually part of the civil engineering project. Different "grouting schools" or "ways of thinking" did develop and a considerable number of recipes were dictated by "great old men" and enforced later on by regulations of any kind. Only in the last...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
Rock Masses as Construction Materials
A rock mass is a material quite different from other structural materials used in civil engineering. It is heterogeneous and quite often discontinuous, but is one of the materials in the earth's crust, which is most used in man's construction. Ideally, a rock mass is composed of a system of rock blocks and fragments separated by discontinuities forming a material in which all elements behave in...
متن کاملMicroplane damage model for jointed rock masses
The paper presents a new microplane constitutive model for the inelastic behavior of jointed rock masses that takes into account the mechanical behavior and geometric characteristics of cracks and joints. The basic idea is that the microplane modeling of rock masses under general triaxial loading, including compression, requires the isotropic rock matrix and the joints to be considered as two d...
متن کاملOptimized Mamdani fuzzy models for predicting the strength of intact rocks and anisotropic rock masses
Development of accurate and reliable models for predicting the strength of rocks and rock masses is one of the most common interests of geologists, civil and mining engineers and many others. Due to uncertainties in evaluation of effective parameters and also complicated nature of geological materials, it is difficult to estimate the strength precisely using theoretical approaches. On the other...
