In this study, we use numerical simulation to analyze the uplift performance and failure modes of two types of rock embedded foundations with different buried depths in strongly weathered areas. We performed uplift bearing capacity tests on rock embedded foundations in Taihu county, Anhui province. The results show that the uplift bearing behaviors and failure modes of jar-type and belled-piers foundations are similar when their buried depths are shallow. When the buried depth of the foundation is deep, however, the uplift bearing behavior of the belled-piers foundation is obviously better than that of the jar-type foundation. In addition, we compare and analyze the economic benefits of these two foundation types. Our research results show that the tensile strength, economy, and environmental protection afforded by belled piers are superior. Therefore, we recommend that belled-pier foundations be applied in transmission line projects with strongly weathered rock foundations.
