联合板索基础抗拔机理及容许上拔力

Anti-tensile mechanism and allowable uplift force of joint plate cable foundation

针对目前使用的既抗压又抗拔基础存在的缺陷和不足,构建了联合板索基础并获得了发明专利授权。在研究联合板索基础与扩底桩基础的抗拔机理基础上,研究了联合板索基础与扩底桩基础所能承受的极限上拔力,通过联合板索基础与扩底桩基础的对比研究,揭示了联合板索基础的抗拔机理,并借助扩底桩基础的上拔力容许设计值和稳定验算公式,解决了联合板索基础设计和稳定验算问题。

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 antitensile 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.
