高铁施工中预应力混凝土连续梁质量控制

Quality Control of Prestressed Concrete Continuous Beam in Construction of High Speed Railway

随着国民经济的快速发展,我国高速铁路建设事业得到了一定的发展。预应力混凝土连续梁作为高铁建设施工中一项重要的施工方法应用较为广泛,尤其是在较宽的河面上修建大跨度梁时,预应力连续梁施工技术能够使梁高得到有效降低,并对梁的挠度有较好地控制,减少或避免了裂缝的产生,使桥梁建筑的施工质量得到提升。因此,做好高铁施工中预应力混凝土连续梁质量控制极为重要。通过分析高铁施工中预应力混凝土连续梁质量控制中存在的问题和解决办法,给相关工作人员提供参考与借鉴。

With the rapid development of the national economy, China＇s high-speed railway construction has also been the development of the corresponding. Prestressed concrete continuous beam as the high-speed railway construction is an important method of construction, widely used, especially the need of construction of large span beam in the wide river, continuous beam construction technology of prestressed beam can make high be reduced effectively, and deflection of the beam control is good, reduce or avoid the cracks, the construction quality of bridge construction has been improved. Therefore, it is very important to do the quality control of prestressed concrete continuous beam in the construction of high speed railway. This paper analyzes the problems and solutions in the quality control of prestressed concrete continuous beam in the construction of high speed railway, and hopes to provide reference and reference for the relevant staff.
