Abstract：
At an altitude of 3220 metres above sea level in Yunan, the muon intensity above2.0 GeV/c was measured at large zenith angles (78.4-90°) by a G-M hodoscope. Atmean zenith angle 86.2°, the measured result was (9.2±1.0)·10^-5cm^-2·sr^-1·s^-1. By a magnetic cloud chamber, the muon spectrum at same zenith angles was mea-sured in the momentum region 2-51 GeV/c.
