Benchmarking of FEM Technique Involving Deep Excavation, Pile- soil Interaction and Embankment Construction
Three case studies involving the use of numerical models are presented in this paper. First, a comparison of FE modelling of a deep excavation is made using 2-D finite element software, SAGE-CRISP and PLAXIS. In the second study, benchmarking is made between results obtained from 2-D FE modelling using PLAXIS and well-established 3-D centrifuge studies for the case of an existing single pile an...
متن کاملPower and Fresh Water Production by Solar Energy, Fuel Cell, and Reverse Osmosis Desalination
This paper presents sizing, energy management strategy, and cost analysis for a configuration consisting of solar photovoltaic (PV) panels, fuel cell (FC) storage system, and reverse osmosis (RO) desalination technology for combined power and fresh water production. In this system, PV is the main power supply source; fuel cell is a storage system accompanied by Hydrogen production and storage d...
متن کاملInvestigation of natural biofilms formed during the production of drinking water from surface water embankment filtration.
Populations of bacteria in biofilms from different sites of a drinking water production system were analysed. Polymerase chain reaction (PCR) and denaturing gradient gel electrophoresis (DGGE) analyses revealed changing DNA band patterns, suggesting a population shift during bank filtration and processing at the waterworks. In addition, common DNA bands that were attributed to ubiquitous bacter...
متن کاملWater Inrush Characteristics with Roadway Excavation Approaching to Fault
Water inrush disaster is an important factor in restricting safe production of the coal mine. Taking the roadway in seam in Danhou Coal Mine, as the engineering background, according to the spatial relationship of the roadway, the impermeable layer, the fault and the loading conditions, the fault activation mechanical model under the roadway excavation disturbance was built, and the fault activ...
متن کاملEmbankment overtopping protection systems
For the last decades, the design floods of numerous embankment reservoirs were re-evaluated, and the revised spillway outflows are typically larger than those used in the original designs. As a result, a number of overtopping protection systems were developed for embankments and earthfill dams, with applications encompassing river dykes, coastal barriers for storm surge and tsunami protections....
