PROBLEM TO BE SOLVED: To provide a method for measuring clogging of a tunnel gutter by wind velocity measurement, which enables quantitative monitoring of a cross-sectional change in the tunnel gutter by making a wind flow through the tunnel gutter, without replacement of the tunnel gutter.SOLUTION: In a method for measuring clogging of a tunnel gutter by wind velocity measurement, an air blast W is introduced into a tunnel gutter 13; a change in wind velocity within the tunnel gutter 13 is measured; and a cross-sectional change within the tunnel gutter 13 is measured on the basis of the change in the wind velocity.SELECTED DRAWING: Figure 2 |
