| 摘 要： | 某桥现浇箱梁需跨越主河道，采用六四式军用梁搭设的梁式支架。即首先在梁底搭设／＼Z式军用墩，并加设临时墩，形成临时支撑体系，然后在临时支撑上架设六四式军用梁、搭设碗扣式支架，进行现浇。对支架体系各个组成部分进行强度、刚度以及稳定性验算，并对临时墩基础进行验算，确保设计可靠、施工安全。为同类桥梁的设计和施工提供了有益的参考。

| Abstract: | Having to span the main waterway of a river, the cast-in-place box girder of a certain bridge adopts the beam-type supports assembled with Type-64 military beams. In this case,type-83 military piers have to be built beneath the girder first, with temporary piers provided,in order to form a temporary supporting system,on which type-64 military beams are to be erec- ted,with the bowl-type supports provided,to get ready for the construction of the site pouring of concrete. The strength, rigidi- ty,and stability of the various composite parts of the supporting system are to be tested, with the foundation of the temporary piers checked, so as to ensure both the reliability of the design and the safety of the construction. |
