Ice load is one of the most dangerous factor which threatens the health of structures on the sea in the cold area.The ice-loading model experiment is an effective method to identify the ice load and evaluate its influence towards the structures.It is important to identify and monitor the ice loads in the model experiment.In this paper,a FBG ice force sensor with enhanced strain sensitivity is presented and applied in the tests of ice loading on bridge pier model.This paper discusses the principle of enhance...
