Cuttings Transport Mechanism in a Large-Diameter HDD Borehole
Publisher: American Society of Civil Engineers
Abstract: Drilling mud (or drilling fluid) is a vital component in a horizontal directional drilling (HDD) crossing project, for which a key function is the removal of the cuttings from the borehole. The rheological properties of ...
Buried Pipe Affected by River Erosion When Crossing the Yangtze River
Publisher: American Society of Civil Engineers
Abstract: Two river crossing cases are considered in which a pipe is installed beneath the Yangtze River using horizontal directional drilling (HDD). In both cases, a length of pipeline located on the rock strata near the north bank, ...
Improved Probabilistic Kinematic Analysis Procedure Based on Finite Size Discontinuities and Its Application to a Rock Slope at Open Pit Mine in U.S.
Publisher: American Society of Civil Engineers
Abstract: An improved probabilistic kinematic analysis procedure is suggested incorporating the six steps listed in the paper. The variability of the shear strength and discontinuity orientation is taken into account in the probabilistic ...
