There are two types of tests conducted for axial types of loading, namely compression tests and pullout (tension) tests. For compression tests, the load can be applied either by adding dead …

Aug 1, 2022 · This paper aims to provide a technical reference for selecting and applying different methods in the pile axial load test for the stability study and bearing capacity assessment of …

Jun 17, 2024 · 1.1 The test methods described in this standard measure the axial deflection of an individual vertical or inclined deep foundation element or group of elements when loaded in …

Axial compression or tension load tests shall be conducted by loading the helical pile/anchor in the load sequence as shown in Table B-4. Anchor/pile head displacement shall be recorded at …

Once the pile load testing is completed, personnel from the Foundation Testing Branch compile and review the load test data. The test data is used to produce a plot of load versus pile …

This document relates to the testing of single piles under axial loading. While services can be offered for the testing of un-instrumented piles, the emphasis in this presentation is on the …

Oct 30, 2025 · Axial load testing determines a material’s strength and stability by applying a force directly along its main axis. This method involves either pulling the material apart (tension) or …

3.2 Definitions of Terms Specific to This Standard: 3.2.1 axial compressive capacity, n—the maximum axial compressive load that a deep foundation can transfer to the soil and rock …

Examples of two accepted load test standards are ASTM D1143 for axial compression loads, and ASTM D3689 for axial tension loads. These standards inform how a load test should (ideally) …

These facts explain the need for load testing of piles, in order to determine the safety level, and potentially improve the design. There are three main types of load tests: static load (applied to …
