SYNCHRO’s complete construction management platform – from 4D construction planning and modeling to cost management to project execution and field performance tracking – can help your team prepare for and meet the IIJA’s Contech goals and requirements.
city of Almaty, Kazakhstan Facts ProjectWise and Bentley’s open applications streamlined workflows and communication, optimizing scheduling across 500 worksites. Leveraging Bentley’s modeling and visualization software facilitated simultaneous design and construction. Project Bringing Gold Production into Kyrgyzstan To eliminate exporting ore for processing and enable gold production within Kyrgyzstan, a decision was made in 2018 to build a gold plant in the mountainous Talas region, nearby the Dzhamgyr mine. The USD 75 million project included constructing the main building, a crushing and screening complex, a laboratory, storage pond, tailings storage facility, poison and ore storage areas, shift camps for operating personnel, and new roadways and accesses. AAEngineering delivered the winning bid for this engineering, procurement, and construction project that was located in a dangerously seismic area. In addition to the altitude and seismicity complications, AAEngineering had to overcome technical, engineering, and coordination challenges, as well as meet strict environmental standards amid a short construction period and an ensuing global pandemic. “Without using ContextCapture and OpenRoads, it is difficult to imagine the possibility of designing the multistage construction sites, on-site engineering works, roads, and highway spirals.” Andrey AksyonovDirector of Information Modeling DepartmentAAEngineering Group Solution Open Applications Provide Integrated Solution AAEngineering selected ProjectWise
Rock at depth is subjected to stresses resulting from the weight of the overlying strata and from locked-in stresses of tectonic origin. When an opening is excavated in this rock, the stress field is locally disrupted and a new set of stresses are induced in the rock surrounding the opening. A knowledge of the magnitudes and directions of these in situ and induced stresses is an essential component of underground excavation design since, in many cases, the strength of the rock is exceeded and the resulting instability can have serious consequences on the behavior of the excavations.
Constitutive modeling of jointed rock masses has long been a subject of interest and numerous models have been developed in attempts to simulate their mechanical responses. There are two groups of these models: discrete models and continuum models as summarized by Cai and Horii (1993):
he Convergence-Confinement Method is a basic and commonly used tool for underground support structures in conventional tunneling during the preliminary stage of design.
The Rock Your Analysis with PLAXIS series will discuss rock engineering applications, their challenges, and the resources that numerical modelers and geotechnical engineers can use to solve these problems by using PLAXIS geotechnical analysis software.
In both analytical and numerical approaches, a significant increment in anchor block pullout capacity was observed after considering the 3D effects over those capacities obtained by considering 2D analysis. As a result, this helps in avoiding underestimation of an anchor block’s pullout capacity and thereby aids in the optimization of anchor block design. In addition, it was promising to note that pullout capacities obtained after considering the 3D effects from both approaches are very close in their magnitudes.
The aim of this article is to demonstrate the suitability of 2D FEM analyses in metro station outer boxes structural element design (even in demanding conditions) with specific reference to the Arlozorov West Station and Rabin Station.
Le Port de Tanger est constitué de caissons en béton armé posés sur un remblai en fond de mer. Les terrains d’assise sont des sables silteux à graveleux épais d’une trentaine de mètres reposant sur le substratum.
