Abstract: The TGP safety monitoring system is asystematic projeet which spreads widely, touches on multi-faeeted things, lasts a long time, and its automation degree is high, its technique is sophisticated. Deformation monitoring system is the most important part in the monitoring system. This paper briefly introduces the deformation monitoring system in TGP, some important technique problems in the deformation monitoring are discussed in detail, and some useful information is summarized to provide areference.
