Based on the temperature compensation method of Brillouin Optical Time-Domain Reflectometer （BOTDR）

specially packaged fibers of temperature sensing were used to detect temperature variations in static load test and strain changes caused by the change of temperature during concrete curing period of bored pile.The research results show that the strain changes due to temperature are small at the end of curing period

indicating that hydration heat has been dissipated;and the same conclusion holds as well in the static load test process.As a result

the strain detection error caused by temperature can be ignored in the distributed fiber optic sensing detection of bored pile.
