RECORDS OF LOAD TESTS ON FRICTION PILES
暂无分享,去创建一个
RESULTS ARE PRESENTED OF 412 LOAD TESTS COMPILED IN A CONDENSED FORM. THE RECORDS ARE CLASSIFIED AND INDEXED IN ACCORDANCE WITH TYPE OF PILE, GENERAL TYPE OF SOIL, AND LOCALITY. BY MEANS OF THESE INDICES, RECORDS CAN BE LOCATED THAT MAY BE OF INTEREST IN JUDGING THE PROBABLE BEHAVIOR OF PILING UNDER SOMEWHAT SIMILAR CONDITIONS. LOAD-SETTLEMEMT CURVES CORRESPONDING TO THE INDIVIDUAL TESTS ARE SHOWN IN PILE TEST DATA SHEETS. RESULTS OF VARIOUS LOAD TESTS HAVE BEEN COMPARED ON THE BASIS OF THE SHEAR STRENGTH ACTUALLY DEVELOPED BETWEEN THE PILE AND THE SOIL DURING THE TESTS. THE SHEAR STRENGTH HAS BEEN CALCULATED BY DIVIDING THE FAILURE LOAD IN EACH TEST BY THE EMBEDDED AREA OF THE PILE. IN THE CASE OF H-PILES THE EMBEDDED AREAS HAVE BEEN CALCULATED ON THE ASSUMPTION THAT FAILURE OCCURS ON THE SIDES OF THE RECTANGULAR PRISM ENCLOSING THE PILE SECTION. RESULTS OF THESE CALCULATIONS ARE PRESENTED.
