Low-strain integrity testing is designed to give information about the physical dimensions, continuity and consistency of materials used in piles. This test method covers the procedure for determining the integrity of individual vertical or inclined piles by measuring and analyzing the velocity response of a pile...

The cross-hole sonic integrity testing is one of the most advanced and economical tools for testing the integrity of drilled shafts. Currently, there is no better method for non-destructively identifying any defect in the drilled shafts. The test determines the quality of concrete between pairs of...

From a drivability analysis, a driving criterion can be developed so that the driven piles can be installed without causing structural damages. Such objectives can be accomplished using GRLWEAP computer program which simulates the pile driving process from GRL Pile Dynamics in the US.   From...

High-strain dynamic testing is performed by obtaining and analyzing records of shaft force and velocity under drop weight impacts for evaluations of pile load carrying capacity, structural integrity, and load-movement and pile-soil load transfer relationship. High-strain dynamic testing is a non-destructive quick test and it is...

This technique does apply while statically testing a vertical compression pile using vibrating wire strain gages. The aim of this technique is to measure the responses to load in the test pile in terms of relative strain responses throughout the pile length. Such pile shall be...

Drilled boreholes, even of rectangular shapes, are rarely of ideal shapes and irregularities in the shaft foundations can affect capacity and design. Using the sonic logging calliper technique, it is employed to verify the verticality, offset as well as actual diameter of bores and depth prior...

Bi-directional static load testing (BDSLT) for piles is the most economical & reliable method for performing loads test and optimization process. Its major advantage is non-requirement of heavy beams and dead loads for the reaction load. In this method the skin and bearing reaction is being...

High-strain dynamic testing is performed by obtaining and analyzing records of pile force and velocity under hammer impacts for evaluations of pile load carrying capacity, structural integrity, load-movement, hammer efficiency and pile-soil load transfer relationship. The hammer used could be of different type, such as diesel,...
