Numerical modeling of the annular failure pressure during HDD in noncohesive soils
One of the critical issues that engineers, contractors, and owners encounter during horizontal directional drilling (HDD) is inadvertent return of drilling fluid (frac-out or hydraulic fracture) to the ground surface when the annular pressure in the borehole exceeds the yield shear or tensile streng...
