由于我国社会经济建设发展速度的进一步提升,预应力空心面板采用自身具备的轻自重、良好的结构性能以及便捷的施工等优势,在高速公路施工中被广泛运用,并被工程行业内逐渐掌握。在高等级公路中发挥着承重构件的作用,与后张法预应力梁板进行对比,其整体性相对较差。其次由于各部分厚度相对较薄,促使在公路施工中,质量控制发挥着关键作用。预应力混凝土空心板在施工过程中不应要运用优质的钢材及可靠的高强混凝土,而且还应对施工技术人员进行了一定程度的要求。
Due to the further development of China’s social and economic development, prestressed hollow panels are widely used in expressway construction due to their own light weight, good structural performance and convenient construction. They are gradually mastered in the engineering industry. In the high-grade highway to play the role of load-bearing components, and post-tensioned prestressed beam comparison, the overall relatively poor. Second, due to the relatively thin thickness of each part, prompting the highway construction, quality control play a key role. Prestressed concrete hollow slab in the construction process should not be the use of high-quality steel and reliable high-strength concrete, but also the construction of technical personnel should be a certain degree of requirements.
