浅析预应力加固技术在桥梁施工

The Prestressed Reinforcement Technology in Bridge Construction

随着社会的发展,车辆数量的越来越多,载重量越来越大,交通运输的负担也在日渐增大,尤其是桥梁工程所承担的负荷。部分桥梁已经老化、破损,原设计承载能力已达不到使用的要求,道路桥梁的建设和维护就显得十分重要。当前公路桥梁的维护广泛地采用预应力加固技术,以提高桥梁的承载能力,达到加固桥梁的目的。本文结合工程实际,针对体外预应力加固法,简要地探讨了预应力加固技术在桥梁施工中的运用及施工。最后根据自身的工作经验,分析在现行预应力加固技术存在的问题。

With the development of society, increase number of vehicles, capacity is more and more big, and the burden of transportation is also increasing, especial y on the load of brid-ge engineering. Part of the bridge has been aging, damage, the original design capacity is not up to the requirements, it is very important to the construction and maintenance of roads and br-idges. Maintenance of the highway and Bridge widely used pr-estressed reinforcement technology, to improve the carrying capacity of the bridge, to reinforce a bridge to. Combined with the engineering practice, in view of the external prestressing strengthening method, briefly discussed the application of pre-stressed reinforcement technology in the construction of bridge and construction. Final y, the author according to the work ex-perience analyzes the problems existing in the current strength-ening technology of the prestressed.
