A brief review of previous studies shows that topographic features play an important role in the amplification (de-amplification) seismic waves. Most researchers who have focused on effects paid attention to distribution isolated features, whereas what is seen nature often more complicated. It known 2D or 3D geological structures further contribute ground motion. The main objective this study i...

Underground mining activity in the karst mountain southwestern China has induced several large-scale rocky landslides and caused serious casualties. At present, there is a lack of systematic research on formation mechanism this area using multi-method fusion technology. First, orthophoto images landslide obtained by UAV photography were used to analyze deformation characteristics landslide. Sec...

Reasonable determination of the ultimate bearing capacity foundation is great significance in engineering applications. Based on self-developed non-contact testing device for plastic zone shallow foundation, this paper carries out model test research sandy soil and analyzes development law under action load. The main advantages functional characteristics system are that it can realize displacem...

Directional long drilling on the roof is an effective gas control measure in goaf, but there little research stability of surrounding rock. In this study, geological conditions #4 coal seam Tingnan Coal Mine, Shaanxi Province, China taken as application background, and deformation characteristics boreholes under four typical rock were first analyzed based Universal Distinct Element Code (UDEC) ...

Abstract The city of Matera, as several other ancient historical cities and towns, is recovering a large part its parts developing policy urban regeneration. In the early 90s, during restoration works main square, Piazza Vittorio Veneto, it was re-discovered huge underground space used water reservoir named Palombaro Lungo . It built linking pre-existing smaller caves completed at end nineteent...

Abstract This paper focuses on the experimental study of shear testing 15.2 mm, 25 t capacity seven wire cables at zero, 30° and 45° angles using two different facilities University Wollongong (UOW) Southern Queensland (USQ) in Toowoomba. A circular double-shear rig MK-IV was used for cable perpendicular to sheared joint faces (zero angle orientation), while carried out a larger-size rectangula...
