摘要
在大跨度结构工程中,后张法预应力混凝土是常见的结构形式。以驮英水库灌区宁明干渠下涧2#渡槽24 m槽身后张法预应力施工为例,论述了后张法预应力混凝土施工工艺和质量控制要点。
Post-tensioned prestressing concrete is a common structure for big-span works.Xiajian No.2 aqueduct of Ningming main channel in Tuoying Reservoir irrigation zone has a span of 24m.Taking the construction of this aqueduct as example,the author demonstrated the construction technology of post-tensioned prestressing concrete and the key points of quality control.
