提出了在桥梁墩顶用钢绞线将结构两边对称拉住的新型抗横力结构,用结构理论和相应的规范进行了验证,使桥梁基本在不增加造价的情况下抵抗住罕遇大地震。
A new type of anti-transverse structure which symmetrically holds the two sides of the structure with steel strands at the top of the bridge pier is proposed. The structure is verified by the theory of structure and the corresponding specifications so that the bridge can basically resist the rare earthquakes without increasing the cost .
