Why does a building on solid bedrock resist better to an ...

2021-10-22  The reaction of a building to an earthquake depends on two major parameters: the technique used for its construction and the kind of ground it is built on. Buildings on solid bedrock tend to shake less than buildings on sediments or reclaimed lands because the bedrock itself shakes less than sediments or reclaimed land. The bedrock vibrates a lot less than sediments because of

Rock-breaking mechanism and experimental analysis of ...

2017-9-1  The rock-breaking mechanism and effect of confined blasting were analysed by blasting and impact dynamic mechanics, fluid dynamic mechanics, fracture mechanics as well as blasting experiment. The results showed that the fracturing of surrounding rock in confined blasting condition is the result of coaction of rock pre-cracking by shock wave and ...

Estimation of Impact Loads in a Hydraulic Breaker by ...

The hydraulic breaker operates by converting the energies of the hydraulic pressure and nitrogen gas into the kinetic energy of the striking pistons. The kinetic energy is then delivered to the rock via the chisel, thereby breaking it. The hydraulic breaker in this study strikes the steel plate (Figure 6(b)) to create uniform impact loads. The ...

Impact of weathering on slope stability in soft rock mass ...

2014-6-1  Abstract. Weathering of soft rocks is usually considered as an important factor in various fields such as geology, engineering geology, mineralogy, soil and rock mechanics, and geomorphology. The problem of stability over time should be considered for slopes excavated in soft rocks, in case they are not protected against weathering processes.

Effect of a Fault Fracture Zone on the Stability of Tunnel ...

The deforming performance and stress distribution of surrounding rock were investigated. Moreover, the stability of surrounding rock in tunnels was analyzed with consideration of the slope angle and the width of the fault. The simulation results indicate that the fault fracture zone in the tunnel can reduce the stability of surrounding rock.
