N2 - Pile load testing provides key information about pile design for a specific geological ground structure. These tests are required to guarantee that the piles will meet long term stability requirements for the foundation of the building. There are many types of sensor that can be used to monitor strain along the pile during pile load testing. The most commonly used sensor is the Vibrating Wire Strain Gauge (VWSG). Each VWSG has its own electrical cable which will have to withstand the concrete or grout pouring stage as well as the curing cycle. By the time the pile is ready for testing, a certain percentage of VWSG signals have often been lost. This paper presents a novel approach using Concrete Embeddable Fiber Optic Strain Gauges. One of the fiber optic based sensor advantage is to be able to daisy-chain the sensors. That is, reducing the number of cables along the pile. The optical cable can also be designed to withstand very harsh environments without adding too much to the cost of the sensors. This paper will also present comparative results as well as future possibilities to reduce cost and time for pile load testing.
