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。
In view of the defects and shortcomings of the existing compressive and anti-pull bases, a combined plate and plate foundation was established and obtained the invention patent authorization. On the basis of studying the anti-pull mechanism of the combined plate and foundation, the ultimate pullout force of the combined plate and foundation is studied. By comparing the plate and foundation Research and reveal the anti-pulling mechanism of the combined plate and plate foundation, and solve the problem of the joint plate and plate foundation design and stability check with the allowable design value and the stable checking formula of the uplift force of the expanded bottom pile foundation.
