Abstract: Geotechnical characterization of potential lunar sites will be a critical part of the planning and design process. The strategies used to conduct a geotechnical investigation will be dictated by the specific needs of the ...

Abstract: A large‐scale group of nine steel‐pipe piles in a closely‐spaced arrangement was subjected to two‐way, cyclic, lateral loading with water above the ground surface. The test was conducted in stiff, overconsolidated clay at ...

Abstract: A large‐scale group of steel pipe piles and an isolated single pile were subjected to two‐way cyclic lateral loading. The tests were conducted in a submerged firm to dense sand that was placed and compacted around the ...

Abstract: When conventional concrete is used in congested drilled shafts, coarse aggregates may bridge between reinforcing bars, which may lead to segregation of the concrete between the inside and outside of the reinforcing cage. ...

Abstract: A common design/construction procedure for highway bridges in Alabama is the use of steel HP piles driven to a firm stratum with a length above ground up to the level of a concrete bent cap which supports the bridge ...
