Instrumented Pile Load Test

(Maintained Load Test, Lateral Load Test, Tension Load Test)

DPT provides load cells, LVDTs and data loggers to measure pile head settlement during Maintained Load Test (MLT). These tests conform to ASTM D1143 (Axial Load Test); ASTM D3689 (Tension Load Test) and ASTM D3966 (Lateral Load Test).

To obtain the unit shaft friction and end bearing, we also provide Vibrating Wire Strain Gauges (VWSG) to measure strain at fixed locations and compute the effective transfer of forces to the various depths of the pile.

Alternatively, DPT provides Distributed Fiber Optic Strain Sensing (DFOSS) technology to obtain the continuous strain profile of the instrumented test pile. This state of the art technology is much superior to the conventional point sensing using VWSG.
