入射

In this paper, the analytical expressions of seismic input for homogeneous elastic half-space are first derived in oblique incidence of plane SV-wave, and then a finite element model for a real hydropower cavern group composed of main powerhouse- transformer chamber- tailrace surge tank cavern is created. Characteristics of seismic responses such as displacement, acceleration and stress are studied in detail at different incidence angles and some results are compared with those given by the literature.

Studies discover that the minimal deposition threshold is 20eV and the maximum is 60eV with the different incidence point locations and incidence postures of C36 clusters. When the incidence angle is not over 60, C36 may roll or slip to the region of smaller bonding energy and then bond. So the bonding probability is raised.
