STATIC PILE LOAD TESTS: CONTRIBUTION OF THE MEASUREMENT OF STRAINS BY OPTICAL FIBER

The use of optical fiber for measuring strain and or temperature is increasing in civil engineering. Optical known to be relatively cheap, compared the more traditional sensors commonly used, can, depending on chosen technology, give a complete distribution along instrumented element, which can very interesting case an element with variable dimensions length said element. Therefore, static pile loading tests, should present many advantages, conventional methods measurements. aim this paper shed new light advantages disadvantages using measurement deformations foundation After review state art most used methods, contribution instrumentation elements evaluated, by comparing results obtained those some examples full-scale load tests. Finally, recommendations are given maximize awareness potential monitoring.
