Reducing-resistance mechanism of vibratory excavation of hydraulic excavator

Journal of Central South University of Technology, 2008
Based on the working principle of vibratory excavation of hydraulic excavator, the expression of digging resistance changed with time under sine wave inspiritment was deduced; a comparison analysis was given after calculating the forces status of rock and soil under static load and vibratory load respectively by using MATLAB; and then RFPA-2D(rock ...

The influence of an excavation damaged zone on the thermal-mechanical and hydro-mechanical behaviors of an underground excavation

Engineering Geology, 2008
In Korea, a reference disposal system, KRS, was proposed in 2006 after 10 years of research and development. In the KRS, the high-level radioactive waste repository is considered to be located in a crystalline rock likes granite. For a validation of the feasibility, safety, and stability of the KRS, an underground research tunnel, KURT was constructed ...

Computational mechanics of the excavation of tunnels

Engineering Computations, 1996
Contains a report on three‐dimensional finite element (FE) analyses of deformations and stresses resulting from the excavation of shallow underground railway tunnels. Multisurface elasto‐viscoplastic material models are employed for consideration of the mechanical behaviour of the soil and the shotcrete shell supporting the excavation.

Application of distributed actuation mechanism to a hydraulic excavator

2014 IEEE International Systems Conference Proceedings, 2014
It has been recently proven that the distributed actuation mechanism, as a new actuation mechanism, provides additional design freedom to maximize the performance of a given system. In this paper, we proposed a new type of hydraulic excavator which adopts distributed actuation mechanism to enhance its excavation performance.

Mechanical Underground Excavation in Rock

2016
Mechanical methods for underground excavation have the most advantage of less disturbance to the surround environment, especially in the urban area and complex ground conditions. Drilling and Breaking method, roadheader, raise boring machines, tunnel and shaft boring machines (TBM & SBM) and Bored pile are introduced in this chapter.
