Abstract:A joint plate cable foundation is established and offered patent of invention to improve the deficiencies of present widely used compression and pulling resistant foundation. Based on the study of anti-tensile mechanism of joint plate cable foundation and belled pile foundation, the ultimate uplift force that the joint plate cable foundation and belled pile foundation can bear is further analyzed. The anti-tensile mechanism of the joint plate cable foundation is revealed through comparatively studying the joint plate cable foundation and belled pile foundation. The issue of designing and verifying the joint plate cable foundation is solved by using the allowable uplift force and the stability verification equation of the belled pile foundation, which provides theoretical and technical support to the promotion of such kind of foundation.
Keywords: plate cable foundation; joint foundation: anti-tensile mechanism: uplift force
