Investigation on the failure evolution characteristics of surrounding rock in deep cross‐fault roadway: Based on physical model test and numerical simulation

Deep Underground Science and Engineering, EarlyView.
This study reveals the failure evolution characteristics of deep cross‐fault roadway surrounding rock under excavation support and periodic weighting. Periodic weighting readily induces fault activation, with the spatial distribution of failed rock masses being controlled by the fault strike and dip.

The direct boundary element method: 2D site effects assessment on laterally varying layered media (methodology)

, 2004
The Direct Boundary Element Method (DBEM) is presented to solve the elastodynamic field equations in 2D, and a complete comprehensive implementation is given. The DBEM is a useful approach to obtain reliable numerical estimates of site effects on seismic

Assessing infrequent large earthquakes using geomorphology and geodesy in the Malawi Rift [PDF]

, 2015
In regions with large, mature fault systems, a characteristic earthquake model may be more appropriate for modelling earthquake occurrence than extrapolating from a short history of small, instrumentally observed earthquakes using the Gutenberg–Richter ...

Climatic drivers prevail in montane and lowland Odonata latitudinal diversity gradients, but human modification erodes lowland patterns

Ecography, EarlyView.
Latitudinal diversity gradients (LDGs) arise from the interplay of historical, ecological, and evolutionary processes, yet these drivers may differ across landforms. Mountains, with steep elevational and climatic gradients, often sustain distinct diversity dynamics compared with adjacent lowlands, where vertical climatic gradients are weak and human ...

Seismic soil-structure interaction for pile supported systems

, 2009
Civil engineering structures involve structural elements with direct contact with ground. When the external actions, such as earthquakes, act on these systems, neither the structural displacements nor the ground displacements, are independent of each ...

Evaluating Seismic Resistance and Energy Dissipation of CFRP‐Reinforced Concrete Frames Under Monotonic Loading

Earthquake Engineering and Resilience, EarlyView.
“It was found that good ductility can be achieved in CFRP‐strengthened frames, and this result was validated through experimental testing.” ABSTRACT Reinforced concrete structures are increasingly vulnerable to deterioration by steel reinforcement corrosion, resulting in severe loss of fracture strength and service life, particularly in severe ...

Seismic response analysis of jointed rock slope under pulse-like ground motions

Advances in Civil Engineering
Abstract Because of the directional effect, energy concentration and hanging wall effect of pulse-like ground motions, it is easy to cause rock fall, collapse, and landslide of jointed rock slope. To reveal the deformation law and failure model of jointed rock slope under pulse-like ground motions, a discrete element numerical model of ...

Rigid Structure Response Analysis to Seismic and Blast Induced Ground Motions

Procedia Engineering, 2011
AbstractComprehensive studies of rigid structure responses to seismic ground excitations have been reported. It was found that the rocking and sliding response of a rigid structure is highly nonlinear. The structure stability depends on the structure slenderness, as well as the ground motion amplitude, frequency and duration.

Seismic soil pile interaction:experimental evidence

, 2009
The comprehension of the real behaviour of pile foundations under earthquake loading is very important, since it can significantly affect the performance of the superstructure.
