Numerical analysis of tunnels and deep excavations
This report covers 33 papers submitted to the session Numerical Analysis of Tunnels and Deep Excavations. The majority of papers (26) addresses aspects related to tunnelling, both NATM and bored tunnels. As compared to previous conferences analysis of interaction between tunnel construction and surrounding structures such as buildings and pile foundations seems to have become more important. On...
متن کاملModelling issues for numerical analysis of deep excavations
The influence of different modelling assumptions on the results of numerical analyses of a deep excavation problem is discussed. Based on a reference solution a comprehensive parametric study is performed, identifying modelling assumptions which may have a significant influence on the calculated displacement behaviour and the bending moments in the wall. The parameters investigated include wall...
متن کاملEvaluation of Seismic Vulnerability of Reinforced Concrete Buildings Adjacent to the Deep Excavations
In this study, the effect of deep excavation on the seismic response of RC moment resisting building systems has been studied. Deep excavation can cause significant changes in the stress and strain levels of soil environment and also changes in the propagation of seismic waves. This leads to permanent displacements in the foundation system. In this study, three RC building systems, i.e. 5, 10, ...
متن کاملNumerical Investigation on Effects of Deep Excavations’ Position on Existing Metro Tunnels in Urban Areas
Nowadays deep excavations are needed for construction of foundation of high rise buildings, providing space for parking and etc. In some cases deep excavations may be constructed in the vicinity of the subway tunnels and causes unpredicted extra displacements and internal forces in tunnel lining of tunnels which were not designed for them and consequently affect serviceability of tunnel. Theref...
متن کاملSelected Aspects of Neutron Decay
Precision measurements of neutron decay offer complementary access to particle physics at small distance scales or high energies. In particular they allow tests of the V-A structure of the weak interaction. Among many experimental activities which are ongoing around the world we present two new experiments which are planned or studied for the near future. While the neutron lifetime still bears ...
