Finite Element Method Analysis of Influence on Subway Tunnel Adjacent to Excavation by Excavation Construction
The interaction influence on subway tunnels adjacent to foundation excavation was produced by excavation construction, and it is great significance for the correct assessment of its size and influence on the safety of subway operation. Based on the foundation excavation project, some typical foundation excavation profiles are selected, the calculation and analysis on additional settlement and h...
متن کاملInfluence of Underground Excavation of Large-Section Intercity Railway Tunnel on Adjacent Pile Foundation
Three-dimensional model is established with finite difference method to simulate construction process based on design and construction plans of existing overpass pile foundation adjacent to certain large-section railway tunnel in Chengdu, China. Ground, isolation pile, main bridge pier and ramp pile near the tunnel are taken as research object, and surface settlement amount, displacement change...
متن کاملAssessment of Tunnel Excavation on Surface Settlement
The expansion of underground structures is important in urban areas with high population density. In most large cities in the world, urban development is spreading along the structures. These structures are generally located at shallow depth; therefore study of shallow tunnels in urban areas is critical for development. During the excavation of tunnels in urban areas, creating the asymmetric se...
متن کاملA 3D Simulation Method of Foundation Pit Excavation Based on Vector Graphics
Vector Graphics is a character of Flex technology, vector graphics-based 3D model has a simple data structure and a fast speed, it's a suitable modeling method for Web3D programming. In this paper we present a polygon automatically blocked and cropped algorithm, to disperse foundation pit. And on this basis we use Flex technology to design a vector graphics-based threedimensional simulation met...
متن کاملAssessment of Soil cohesion of Soils on Tunnel Excavation
Excess pore pressure under seismic loadings has always been a main concern in geotechnical engineering practices. Undergoing the phenomenon in a soil can cause the effective stress and hence the shear strength of the soil to decrease considerably and large deformations happen in the area. Generally, increasing the pore pressure occurs under the undrained condition. If it can be formed the drain...
