There are plenty of times when you'll wonder why you had to open this door and not the other identical one you just passed, or when an area opens out into a large room full of conveniently cover height crates that instantly telegraphs the upcoming fight.
Sagebrush cover, height, and canopy area were greater at higher levels of crested wheatgrass control.
The geometric configuration of the pipe trench, including the cover height and trench width, significantly influenced the overall deformations of the soil-pipe system.
In this study, as a loading set, working pressure, transient pressure, vacuum pressure, soil cover height, ground water, and surface live load are used.
For spans greater than 18 m the demand for cover height rapidly increases and it appears to stabilize at h/B=1.0 for B=26 m and above.
CHAID and quantile regression procedures were used for obtaining mean and maximum response models, respectively, of shrub characteristics (cover, height and fine fuel load).
Our results indicate that for cavern spans of up to 18 m a low cover height vs. opening span ratio of h/B=0.33 is sufficient for stability.
We perform numerical analysis of multiple roof spans vs. cover height geometries using the DDA method to obtain the boundary curve between stable and unstable opening geometries.
This paper presents full scale pipe-soil tests results and finite-element parametric studies conducted to investigate the effects of soil moisture content, dimensionless cover heights (soil cover height to diameter ratio) and soil relative density on the peak uplift resistance of pipes.
The key outcomes of this performance evaluation model can be summarized as follows: The geometric configuration of the pipe trench, including the cover height and trench width, significantly influenced the overall deformations of the soil-pipe system.
