Description GRLWEAP is a one-dimensional "wave equation analysis" program for simulating a foundation pile under the action of an impact or vibratory driving hammer. The program computes: the blow count (number of hammer blows / unit length of permanent set) of a pile under one or more ultimate resistance values and other dynamic soil resistance parameters, given a hammer and driving system; the axial stresses in a pile corresponding to the computed blow count; the energy transferred to the pile. Based on these results the program derives: the pile's bearing capacity at the time of driving or restriking, given its penetration resistance (blow count); the stresses in a pile and therefore an assessment of the likelihood of pile damage. Given unit skin friction and end bearing the program calculates the blow count at various points during driving and associated maximum stresses. It allows the user to investigate which hammer is likely to be sufficient and economic for a certain pile and soil condition prior to mobilizing the hammer to the job. Preprogrammed reference files of hammers are called by a single ID number, extensive user help, and numerous automatic features (such as building the pile model). Extended options include driveability analysis, different stroke options for diesel hammers, soil sensitivity analysis, and models for parallel or composite piles. Output includes bearing graph, drivability graph, stroke (or hammer energy) versus blow count. Allows for analysis of piles with splices, slacks, cushions and other material interfaces, as well as composite piles.
