Three-dimensional calculation method which can truly reflect the actual situation of Used in cross-sectional design, and meanwhile, can be used to get the most unfavorable position ofįorce distribution, displacement, and surface subsidence, basement uplift, and many other designĬoncerns. Geological excavation is increasing daily, designers desire that the results o f the analysis can be However, with the development of foundation pit engineering, deep, large-scale and complex On elastic method, and the applied effect is good in practical engineering.
#Ellipse flac3d software#
At present, the mainstream pit analysis software is based State, so this method has been widely used. The finite element method of elastic foundation is common for deep excavation analysis which canĮffectively simulate various factors in excavation process, and the results is close to the actual stress The results can provide a usefulĪssistance for design and can also be used as the basis for scientific analysis. Structure and ground settlement can be accurately calculated.
A meshing method is developedįor arbitrary planar domain, and the three-dimensional stratigraphic model is established.Ĭonsidering the interaction between soil and structure, the force and deformation of supporting With the requirements of different specifications by the programs.
Force calculation, section designĪnd stability analysis, and force diagram generation of support structure can be done in accordance With the Three-dimensional finite difference software FLAC3D. Section design programs were developed to meet the needs of foundation design and calculation Two-dimensional and three-dimensional calculation methods of deep excavation, and School of Civil Engineering, Beijing Jiaotong University, Beijing, 100044, ChinaĬCCC First Highway Consultants Co., LTD Xi’an, 710075, Excavation, FLAC3D, Three-dimensional stratigraphic model, Numerical analysis,Ībstract.
