Annular Fluid Pressure Analysis of the Sabine Neches Levee Direct Pipe Crossing
This paper presents an evaluation of and compares the observed annular fluid pressures to the predicted annular fluid pressures as related the risk of hydraulic fracture of subsurface soils observed during the construction of a landmark direct pipe (DP) installation under a U.S. Army Corps of Engineers (U.S. ACE) regulated hurricane protection levee in Port Arthur, Texas. It also provides an evaluation of the relationship between annular fluid pressure and the thrust and face contact forces observed during construction. The Sabine Neches waterway and hurricane flood protection levee crossing in Port Arthur, Texas was completed in April 2015 using DP trenchless construction. With an as-built horizontal length of approximately 3,457 feet, the 48-inch-diameter DP became the largest DP crossing completed to date in North America. It also is the first DP crossing permitted by the U.S. ACE to cross a U.S. ACE-regulated levee and the first DP to incorporate annular pressure monitoring to document the annular pressures and associated risk of hydraulic fracture of subsurface soils during construction.
