作为重要的交通基础设施,桥梁给人们带来了出行的方便。在经济流通速度加快的当今,各地桥梁施工正在如火如荼的进行。在桥梁的施工技术选择上,预应力张拉法被广为采用。而以混凝土结构出现的预应力技术以其成熟的技术,保证了车辆、人员的通行安全。采用此技术,桥梁的受力功能得到加强,在不增加桥梁重量的前提下,抗震、抗裂能力也有效的提升。张拉作为预应力中重要的施工步骤,具有较高的工序要求,如果技术稍有不慎,可能会引发安全事故。所以,做好预应力张拉法的技术施工,尤为重要。
As an important transportation infrastructure, bridges give people the convenience of traveling. At an accelerated pace of economic circulation, bridge construction around the world is in full swing. Prestressed tensioning method is widely used in the choice of bridge construction technology. The prestressed technology that appears in the concrete structure, with its mature technology, ensures the traffic safety of vehicles and personnel. Using this technology, the bridge’s force function has been strengthened, without increasing the weight of the bridge under the premise of earthquake resistance, crack resistance is also effective to enhance. Tension as an important pre-stress construction steps, with high process requirements, if the technology is a little careless, may lead to accidents. Therefore, good prestressed tensioning technology construction, is particularly important.
