读水利水电技术1981年第9期曾广骝同志的《等截面圆弧空腹无铰拱合理拱轴的选择与计算》一文,觉得文中提出的简化计算力系及简化计算方法等内容对于提高计算效率、避免冗繁手续确是很有帮助的.现提出如下几点意见可供曾广骝同志以及从事渡槽、拱桥等的工程人员参考和探讨.1.在外力计算的简化中, The article entitled “Selection and calculation of rational arch axis of constant cross-section arc-free non-hinged arch” by Comrade Zeng Guangli, I feel that the simplified calculation of force system and simplified calculation methods proposed in the paper are of great significance for improving calculation efficiency, It is indeed helpful to avoid cumbersome procedures and the following points are put forward for reference and discussion by Comrade Tseng Kuan-tai and those working on aqueduct, arch bridge, etc. In the simplification of external force calculation,
