Finding pulsars in binaries is important for measurements of the masses of neutron stars (NSs), for tests of gravity theories, and for studies of star evolution. We are carrying out the Galactic Plane Pulsar Snapshot survey (GPPS) by using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). Here we present the Keplerian parameters for 116 newly discovered pulsars in the FAST GPPS survey and obtain timing solutions for 29 pulsars. Companions of these pulsars are He white dwarfs (WDs), CO/ONe WDs, NSs, main sequence stars and ultra light objects or even planets. Our observations uncover eclipses of eight binary systems. The optical counterpart for the companion of PSR J1908+1036 is identified. The Post-Keplerian parameter $\dot{\omega }$ for the double NS systems PSR J0528+3529 and J1844-0128 have been measured, with which the total masses of the binary systems are determined.
