Sentence examples for vertical excavation from inspiring English sources
The lining analysis also demonstrated the effects of the vertical excavation stages and how different safety assessment methods can produce significantly different results.
It is worthy noting that there is a large difference in effective utilization of deep ground pressure between horizontal and vertical excavation directions.
The results indicated a major influence of the height of the vertical excavation stages on the shaft behaviour, markedly on the induced settlements.
The distribution characteristics of displacement fields and plastic zones of the orebody were simulated in three different excavation cases, including the case of excavation artificial inducted roadway in the orebody, the case of horizontal or vertical excavation direction and the case of the upward or downward excavation order.
In this study an attempt has been made to have a deep vertical excavation on ground of 10 m height using soil nail wall.

This will potentially lead into a design tool that adequately account for the stress structure interaction on the stability of vertical or near vertical excavations in hard rock.
This paper presents an implementation of a comprehensive engineering approach to the analysis of the stability of vertical excavations in rock.
A complete integration of the 3D fracture system, which linked the 3D fracture system into a 2D PFC model, was provided, and a 3D SRM model was subsequently formed to analyze the stress structure interaction on the stability of vertical excavations in hard rock (Hadjigeorgiou et al. 2009).
Laming-Emperaire had an eminent thesis adviser, André Leroi-Gourhan, who revolutionized the practice of excavation by recognizing that a vertical dig destroys the context of a site.
By using an axisymmetric lower bound finite element limit analysis formulation, the stability numbers (γH/c) for an unsupported vertical circular excavation in a cohesive frictional soil have been generated.
