Long-connected simply-supported variable continuous beam bridge locally adopting UHPC (Ultra High Performance Concrete) and construction method thereof
The invention discloses a long-connected simply-supported continuous beam bridge locally adopting UHPC and a construction method thereof.The long-connected simply-supported continuous beam bridge comprises an NC foundation, bridge piers and a main beam, the top of each bridge pier is fixedly connected with the main beam, the bottom of each bridge pier is fixedly connected with the NC foundation, each bridge pier comprises a main pier and a side pier, each side pier comprises a UHPC-NC combined bridge pier section and an NC bridge pier section, and the UHPC-NC combined bridge pier section is fixedly connected with the main beam. The UHPC-NC combined pier sections are formed by combining ultra-high performance concrete and common concrete and located at the tops and the bottoms of the side piers. The NC bridge pier sections are made of common concrete and located between the UHPC-NC combined bridge pier sections. The construction method is used for constructing the long-connected simply-supported continuous beam bridge. According to the method, the excellent mechanical property of UHPC is fully utilized, UHPC is reasonably adopted in part of bridge structures, the problem of cracking of the abutment pier can be effectively solved, the construction steps are simplified, the construction period is greatly shortened, and the construction quality is improved.
本发明公开了一种局部采用UHPC的长联简支变连续梁桥及其施工方法，长联简支变连续梁桥，包括NC基础、桥墩和主梁，所述桥墩墩顶与主梁固定连接，墩底与NC基础固定连接，所述桥墩包括主墩和边墩，所述边墩包括UHPC‑NC组合桥墩节段和NC桥墩节段，所述UHPC‑NC组合桥墩节段由超高性能混凝土与普通混凝土组合形成，位于边墩的顶部与底部；所述NC桥墩节段由普通混凝土制成，位于UHPC‑NC组合桥墩节段之间。施工方法用于施工上述长联简支变连续梁桥。本发明充分利用UHPC优异的力学性能，在部分桥梁结构中合理地采用UHPC，能有效避免边墩开裂的问题，并简化施工步骤，大幅缩短施工周期，提升施工质量。
