Abstract

According to the regional tectonic evolution in northeastern Sichuan Basin, Huanglongchang structure is the result ofmultiphase tectonic movements, and it is mostly affected by the force from NE to SWduring the late Himalayan movement. The finite element method and Mohr-Coulomb criterion are used to predict the fractures at the bottomof T1 f 4 in Huanglongchang structure. The result shows that the fractures are well developed in structural high and nearby, two sides of fault, as well as the intersections of faults. Underwent two periods of tectonic stress, six groups of fractures are formed in Huanglongchang structure, and the main trends of these fractures are NW, NE, NNE and NNW.
