| Abstract: | In this paper we present the results of the study on the compositions, structures, and seismic reflection of the preferred faults at Jiajiang and Shiyezhou sites of Zhenjiang-Yangzhou highway bridge foundation, as well as the results of the quantitative observation of the microstructural features of fault gouges from these faults by means of scanning electron microscopy (SEM). The segmentation of these faults has been further studied in the light of the preferred plane theory. The compositions and types |
