Excavation of an Underground Theater below the St
This paper describes part of the construction of a second theater in the underground museum complex, below the Gateway Arch in St Louis. Given the needs for relatively quiet, non-intrusive rock removal, and yet precise cutting within the museum complex a method of using low pressure (35 MPa) abrasive laden waterjets was developed for cutting the vertical walls of the theater down to a depth of ...
متن کاملDevelopment of a Mobile Manipulator for Underground Excavation Task
A national research and development program on Underground Development Technology has started in 1989. In this program, a basic study of a excavating robot has been done at the Mechanical Engineering Laboratory. This paper describes an experimental mobile manipulator for the excavating task. Four legs and a pair of crawlers are equipped with the mobile platform, and a manipulator is set on it. ...

متن کاملAdjoint centroid-moment tensor inversions
S U M M A R Y We determine centroid-moment tensor (CMT) solutions by minimizing waveform differences between observed and simulated seismograms based on an adjoint method. Synthetic seismograms and Fréchet derivatives are calculated based on a spectral-element method. The non-linear adjoint CMT inversion algorithm requires three simulations for each iteration: one ‘forward’ simulation to obtain...
