H-BEARING PILES IN LIMESTONE AND CLAY SHALES
Additional experience and field data related to H bearing piles in limestone and clay shales are presented. In the construction of a 6-story parking garage, a pile foundation was found to be feasible and cost less than a caisson foundation. Some factors relating to the use of driven piles into pinnacle limestone and shale areas are as follows: pile length variations typical of many limestone regions can occur within short distances (eg. the width of a pile cap) as well as over the entire site; damage will occur to unreinforced pile tips; when piles are driven into shale deposits, redriving may be necessary to properly seal the pile; piles tend to move laterally and have greater variation from the vertical than when used under more uniform subsurface conditions. A pile test program was designed which would provide a basis for establishing: the pile hammer size and type; relationship between driven length and drill log information; pile size; point protection, if required; design (allowable) pile load; allowance for lateral movement of pile top; and pile-driving criteria. Laboratory tests for rock include tensile strength determined by double-punch and unconfined strength tests. Details of tests are briefly outlined. Results of the study led to the recommendation for use of H-pile with steel Pruym point pile-tip.
