Dynamic Load Testing is a fast, reliable, and cost-effective method of evaluating foundation bearing capacity. YJACK can perform Dynamic Load Testing on driven piles, drilled shafts, auger-cast piles, micropiles, helical piles, and other cast-in-place foundations. It is often possible to conduct several dynamic load tests in a single day. In addition to bearing capacity, Dynamic Load Testing provides information on resistance distribution (shaft resistance and end bearing) and evaluates the shape and integrity of the foundation element.
The Dynamic Load Test involves a substantial ram mass that impacts the top of the foundation and causes it to experience a small permanent set. Prior to the test, YJACK recommends an adequate hammer or drop weight. If neither is available, YJACK supplies one of its testing systems.
Accelerometers and strain transducers attached to the foundation measure force and velocity as the drop weight hits it. Instead of strain transducers, YJACK may also use a force transducer, which speeds up the test and in certain cases may yield more accurate force measurements. Data is further analyzed with the CAPWAP® software. YJACK engineers furnish a detailed report for each Dynamic Load Testing project that includes a simulated static load test in the form of a calculated load-set curve.
Dynamic Load Tests adhere to the ASTM D4945 Standard Test Method for High-Strain Dynamic Testing of Piles. The test can also be adapted to comply with the Rapid Load Test standard ASTM D7383, given the availability of a suitable ram.
Our HSPLT test employs MrGeo - High Strain Pile Load Tester, an advanced technology providing substantial benefits to stakeholders in the pile testing industry.
The High Strain Pile Load Tester (HSPLT) 2-in-1 is a state-of-the-art testing equipment to perform:- 1. High strain pile load test (HS) on deep foundation piles to measure force (F) and velocity (V) signal to determine pile load capacity base on CASE method (1960s) and YLOAD method (2000s) 2. The Low Strain Pile Integrity Tester (LSPIT) is a state-of-the-art testing equipment to perform low strain pile integrity test (LS) on deep foundation piles.
