An automatic process for estimating ground stability and settlement of circular tunnels is developed practitioners in this paper using finite difference method FLAC code. The numerical model aims to simulate the movement relaxation soil around shield lining annulus that occurs due overcutting grouting tunnel void by a boring machine. To achieve this, uses pressure technique progressively reduce...

Abstract In this essay, the progressive collapse resistance of reinforced concrete wall-frame structures was evaluated with and without considering soil–structure interaction. The vulnerability frames against investigated middle column removal scenario from first story, based on sensitivity index. To evaluate effects interaction, along soil (hard soil) foundation were simultaneously modeled in ...

Abstract Calculation of the bearing capacity shallow foundations on rock masses is usually addressed either using empirical equations, analytical solutions, or numerical models. While laws are limited to particular conditions and local geology data application solutions complex by its simplified assumptions, models offer a reliable solution for task but require more computational effort. This r...

Geologic disposal is a promising solution for safe permanent isolation of accumulated high-level nuclear waste from powerplants. The behavior host rock highly coupled thermally, hydromechanically, and chemically. Numerical simulations such phenomena the extremely long term (>100,000 years) large length scale (>1 km) geologic remain to be computationally challenging. In this study, methodology h...

Recycled materials like Bauxite Residue (Red Mud) and Fly Ash are prevalent in recent feasibility studies on reused geotechnical engineering applications. Red Mud is a mining waste from aluminum manufacturing, by-product of coal combustion power plants. Nevertheless, to fully reveal the using those for constructing above-ground earth structures, better understanding their unsaturated performanc...

Abstract With the increasing depth and intensity of coal mining, impact on ground pressure has become one main disasters facing seriously threatening mine safety. Introducing concept toughness urban design, building a joint prevention control system based active prediction analysis risk at back mining face according to geological deposit conditions technology passive warning using monitoring da...

This paper presents an experimental and numerical analysis of the uplift resistance pipelines buried in reinforced soil. The behavior system is studied using a set laboratory experiments. pull-out forces some reinforcing are most important factors affecting resistance. Buried elements such as that have high pressure fluids or under temperature need to be order increase their One efficient metho...
