Numerical simulation of water entry of tunnel cross section with different deadrise angles and tunnel radiuses
This study deals with the numerical modeling of symmetrical water entry of tunneled sections. In this study, firstly, the water entry problem of a wedge section without tunnel in four different deadrise angles was numerically modeled. The obtained results related to the pressure distribution on these sections and the maximum pressure have been compared with the experiment results. In the next s...
متن کاملUsing Clustering and Factor Analysis in Cross Section Analysis Based on Economic-Environment Factors
Homogeneity of groups in studies those use cross section and multi-level data is important. Most studies in economics especially panel data analysis need some kinds of homogeneity to ensure validity of results. This paper represents the methods known as clustering and homogenization of groups in cross section studies based on enviro-economics components. For this, a sample of 92 countries which...
متن کاملRoof Tunnel Stability by Wedge Analysis
A jointed rock mass presents a more complex design problem than the other rock masses. The complexity arises from the number (greater than two) of joint sets which define the degree of discontinuity of medium. The condition that arises in these types of rock masses is the generation of discrete rock blocks, of various geometries. They defined by the natural fracture surfaces and the excavation...
متن کاملStability Analysis of Non-Local Euler-Bernoulli Beam with Exponentially Varying Cross-Section Resting on Winkler-Pasternak Foundation
In this paper, linear stability analysis of non-prismatic beam resting on uniform Winkler-Pasternak elastic foundation is carried out based on Eringen's non-local elasticity theory. In the context of small displacement, the governing differential equation and the related boundary conditions are obtained via the energy principle. It is also assumed that the width of rectangle cross-section varie...
متن کاملArray Section Analysis
Array sections describe the set of array elements that are either read or written by program statements. An important aspect in such analyses is to formulate a method for describing these sections. Various factors influence the choice of a particular method: factors such as precision, efficiency and practicality. Precise analysis can render high quality solutions and is therefore desirable. But...
