Extra-high voltage transformer substation foundation settlement monitoring method using distributed optical fiber sensing technology
The invention discloses a method for monitoring foundation settlement of an extra-high voltage transformer substation by using a distributed optical fiber sensing technology. The method comprises the following steps of S1, laying a ground surface deformation monitoring optical cable; s2, laying a depth deformation monitoring optical cable; s3, laying foundation pile settlement monitoring optical cables; s4, connecting optical cables are arranged; s5, performing segmented monitoring on the optical cables in the steps S1 to S4; s6, setting a judgment benchmark, carrying out grading treatment on the foundation acquisition data, and carrying out integration and comparison to finish settlement judgment; an optical cable monitoring system is used for mastering an influence rule of a geological foundation on substation equipment and providing an auxiliary decision-making and evaluation means for preventing and treating foundation settlement of a substation; the current position and the relative position of the earth surface optical cable are used as basic data of settlement monitoring, and a calculation basic index is used for subsequent transformer substation earth surface settlement displacement calculation and monitoring, so that a monitoring result and a settlement judgment result are more accurate.
