3D Modelling of Under Ground Burried Objects Based on Ground Penetration Radar

There is a growing demand for mapping and 3D modelling of buried objects such as pipelines, agricultural hetitage, landmines and other buried objects. Usually, large scale and high resolution maps from these objects are needed. Manually map generation and modeling of these objects are cost and time consuming and is dependent on lots of resources. Therefore, automating the subsurface mapping and...

Assessment 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...

Assessment 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...

Effects of the Soft Rock Pre-consolidation on Time-dependent Deformations around the Tunnel Excavation

Original scientific paper Time-dependent deformations in soft rocks represent an important part of total deformations which occur after excavation of the tunnel opening. In the light of this, comprehensive laboratory uniaxial creep tests were performed on marl rock monolits. The testing used marl as a chosen representative rock samples of the group of soft rocks which exhibits creep behaviour. ...

Soft tissue modelling from 3D scanned data

Human body 3D scanners are becoming a mature technology that generates accurate static photo-realistic 3D models of real human beings. However the data collected allow only the construction of the outer surface of the body. In this paper we describe how from 3D surface data we generate 3D volumetric meshes of soft tissues suitable for the finite element method (FEM). We then deform these meshes...
