原文用矩阵力法对拱渡槽进行整体内力计算,这对进一步认识该结构的受力特点和改善工程设计都有益处.笔者在欣读原文后尚有以下几点看法提出来商榷: (一)原文提出的“整体分析”方法能否用来计算横向联系及主拱圈(拱波、拱板、拱肋)的横向内力,是值得怀疑的.因为分析横向内力只考虑竖移协调是不够的.众所周知,拱既受轴力又受弯矩,二者的荷载横向分布规律不同,其对拱的挠度的影响也不同.文献1)对此有详细分析.此外由
The original use of matrix force method to calculate the overall internal arch arch aqueduct, which further understanding of the structure of the force characteristics and improve the design of the project are beneficial.After reading the original article I have the following views put forward to discuss: (a) It is questionable whether the “holistic analysis” method proposed in the original text can be used to calculate the lateral forces and the horizontal internal forces of the main arch (arches, arch plates, arch ribs) because it is not enough to consider only the vertical displacement coordination As we all know, the arch is subject to axial force and bending moment, the load distribution of the two different, which has different effects on the arch deflection.References1) for a detailed analysis of this
