numerical modeling
<p>Due to the importance of surface and subsurface settlements to prevent damages to building foundations and sensitive structures in the urban cities, in this study, the ABAQUS finite element software has used to conduct a series of numerical modeling analysis on ground surface settlement caused from the asynchronous excavation of twin-tunnel. The effects...

<p><span style="mso-ansi-language: EN-US;" lang="EN-US">The behavior of tunnels in anisotropic rock masses is highly complex and heavily dependent on the orientation of the tunnel axis with respect to the geostatic principal stress directions and to the rock structural planes. 2D solutions cannot capture the 3D face effects of such complex scenario; ...

<p>Steel pipe umbrellas have been used to tunnel in difficult conditions or in weak rock masses and/or soils. Despite<br /> the large number of applications around the world, there are still some doubts concerning how pipe umbrellas behave under<br /> loading when the tunnel face advances. For this reason, a scale laboratory model of pipe umbre...

<p>Deposit formation back analysis of a two-year iron ore slime impoundment managed by the sub-aerial method is<br /> performed using two complementary approaches. The first one tries to identify the deposit stratigraphy and its formation<br /> history. This is made possible through sorted document review (reports, design documents, personal co...
