description The invention discloses a method for attaching normal temperature strain gauges to guide tubes of a fuel assembly. The method mainly comprises the following steps: the strain gauges required to be attached are detected one by one and numbered; inner-layer guide tubes, outer-layer guide tubes and angle guide tubes are welded and mounted, and the strain gauges are attached to the welded guide tubes; the attachment quality of the strain gauge on each guide tube is checked; strain gauges are attached to an upper tube base and a lower tube base of the fuel assembly; the strain gauges on the guide tubes, the upper tube base and the lower tube base are detected; tails of leading wires of the strain gauges are processed; the leading wires of the strain gauges are pressed and connected on bridge boxes of the strain gauges, so that the strain gauges are powered up to be electrically connected with data signals. A real fuel assembly structure is adopted for quantitative strain test experiments on the premise that the st
