From the teleseismic P-waveform data recorded at the dense mega seismic array deployed in the western Sichuan area by the State Key Laboratory of Earthquake Dynamics, Institute of Geology, China Earthquake Administration, the authors investigate the crustal anisotropy beneath the stations using waveform correlation method and weighted stacking method. As a preliminary result, the authors measured the fast polarization azimuth and time delay of the Ps converted wave in the receiver functions at 4 stations on both sides of Longmen Mountain Faults. The results can be used for interpreting the single-side rupture of the Wenchuan earthquake and the aftershock evolution.
