This paper presents a numerical analysis of the seismic behaviour of earth dams. Analysis is conducted for the solid phase. It may correspond to the response of the dam before water filling. Analysis is conducted for a simple case which concerns the elastic response of the dam. Numerical analyses are conducted using the FLAC3D program. The behaviour of the Shell and core of the dam and the foun...

After the wenchuan earthquake, dynamic response law of rock slope under action load is a very concerned and urgent problem in field seismic engineering. This paper analyzed simplified cosine wave by numerical simulation with FLAC3D software. research emphatically variation amplification coefficient displacement, acceleration velocity condition different height, angle, period amplitude, which pr...

Buried pipes in the modern societies are considered as lifelines with a vital and essential role in the human life cycle. The performance of buried pipes is affected by many factors such as ground surface subsidence. In this paper, the effect of subsidence on pipelines is investigated using a three-dimensional numerical modeling developed in FLAC3D software for four types of most commonly used ...

The influence on tunnel construction of karst and underground rivers is always an important problem in engineering. In order to demonstrate the rationality backfill parameters effectiveness supports under groundwater when a passes through large cave, finite element software FLAC3D was used for numerical analysis. Converting mean values standard deviations mechanical response results surrounding...

Based on the FLAC3D numerical software, a roadway excavation and support model was established. The stability of surrounding rock FRP bolt force characteristics in Yuhuasi mining area Jinshandian Iron Mine were analyzed. distribution law plastic zone simulated, deformation simulated. data for 6 months tested site, weak links determined, optimized. Parameters, optimized effect is better, which p...

In this study, based on the engineering background of No. 8222 working face Tashan coal mine in Shanxi Province, China, true triaxial experiments were carried out Geotechnical Consulting and Testing Systems rock mechanics testing machine using cubic samples, numerical simulation was conducted through FLAC3D software. Moreover, stress evolution law different layers extra-thick seams failure mech...

This paper presents the methodology in which two computer codes—TOUGH2 and FLAC3D—are linked and jointly executed for coupled thermal–hydrologic–mechanical (THM) analysis of multiphase fluid flow, heat transfer, and deformation in fractured and porous rock. TOUGH2 is a well-established code for geohydrological analysis with multiphase, multicomponent fluid flow and heat transport, while FLAC3D ...
