The invention relates to a double-limb pier bent cap which comprises a bent cap body. Two longitudinally separated stand columns are arranged at the bottom of the bent cap and arranged on a bearing platform, and a foundation is arranged below the bearing platform. The bent cap can be of a common reinforced concrete structure or a prestressed concrete structure. The stand columns have reinforced concrete solid structures, the side length of the cross section of each stand column in the transverse direction of the bridge is larger than that of the cross section in the longitudinal direction of the bridge, the stand columns are divided into two independent stand columns in the longitudinal direction of the bridge to form double-limb piers, and the centers of the two stand columns correspond to the upper structure supports in position. The double-limb piers and a group of pile foundations composed of cast-in-situ bored piles are in structural transition through the bearing platform, and the two ends of the double-limb piers should be fixedly connected with the bent cap and the bearing platform respectively. The anti-bending rigidity of the structure in the bridge direction can be greatly reduced, the structural anti-seismic property objective is achieved, the construction cost is saved, the under-bridge driving view is enlarged, and the structure is safe, reliable, economical and attractive.
本发明涉及一种双肢墩盖梁，包括盖梁；所述盖梁底部设有两个纵向分离的立柱，同时立柱置于承台，承台下面设置基础。盖梁可为普通钢筋混凝土结构或预应力混凝土结构；立柱采用钢筋混凝土实心结构，其截面的横桥向边长应大于顺桥向边长，在顺桥向分开为两个独立的立柱而形成双肢墩，两个立柱的中心分别与上部结构支座位置相对应；双肢墩与一组由钻孔灌注桩构成的群桩基础之间采用承台进行结构过渡，双肢墩的两端应分别与盖梁和承台之间采用固结的连接方式。本发明能够大大减小结构顺桥向的抗弯刚度，实现结构抗震性能目标，节约了工程造价，增大了桥下行车视野，确保结构安全可靠、经济美观。
