近年来冷却塔规模不断增大、进风口不断增高、斜支柱不断增长，这使得传统型斜支柱截面尺寸和混凝土用量大幅度增加，凸显出其用于高进风口时的不合理性。对实际工程中使用过的各类斜支柱方案进行分析，并提出3种新型斜支柱方案，对已有的和新提出的各类斜支柱的特点和选用条件进行探讨，推荐了合理、适用的斜支柱类型。

In recent years, the tower scale, the height of air inlet, the length of diagonal strut become larger and larger. The traditional diagonal strut is not suitable for high air inlet, due to the significant increase of the section dimensions and concrete amount of traditional diagonal strut. Based on the analysis of all kinds of diagonal strut programs used in practical engineering, three new diagonal strut programs were proposed. This paper discussed the feature and select condition of all kinds of diagonal struts in order to recommend the suitable diagonal strut.
