Prediction of maximum surface settlement caused by earth pressure balance shield tunneling using random forest

Due to urbanization and population increase, need for metro tunnels, has been considerably increased in urban areas. Estimating the surface settlement caused by tunnel excavation is an important task especially where the tunnels are excavated in urban areas or beneath important structures. Many models have been established for this purpose by extracting the relationship between the settlement a...

Strain Broadening Caused by Dislocations

Numerous experiments have shown that strain broadening caused by dislocations can be well described by a special logarithmic series expansion of the Fourier coefficients of Bragg reflection peak profiles. In the present work it will be shown that this formalism can be incorporated into the classical methods of Williamson-Hall and Warren-Averbach. The new procedures are suggested to be called mo...

VIEWPOINT 3 D Imaging of Dislocations

D islocations are one of nature’s most elusive crystal defects. But new research from Daniel Hänschke at the Karlsruhe Institute of Technology, Germany, and colleagues [1] promises a way to unlock their secrets. The researchers combined several imaging techniques to provide a 3D view of a network of dislocations (Fig. 1) at an impressive level of detail and over an imaging volume that is orders...

Dispersion of Torsional Surface Wave in a Pre-Stressed Heterogeneous Layer Sandwiched Between Anisotropic Porous Half-Spaces Under Gravity

The study of surface waves in a layered media has their viable application in geophysical prospecting. This paper presents an analytical study on the dispersion of torsional surface wave in a pre-stressed heterogeneous layer sandwiched between a pre-stressed anisotropic porous semi-infinite medium and gravitating anisotropic porous half-space. The non-homogeneity within the intermediate layer a...
