一、引言双曲拱坝选型后,随后的设计常常遇到几何形体计算,比如:分缝计算、分块方量计算、开挖坐标计算、各高程拱的形体计算等等。这里的分缝分块计算,由于带有人为的因素,因此,存在一个合理的分缝方案的问题,我们结合某工程设计进行了初步分析,提出了取各高程拱中心线与顶拱径向线交点的连线为扭转轴(广义意义下)而形成径向缝的方案,显然,双曲拱坝形体计算不仅工作量大,而且很容易出错,为了提高设计质量,加快设计进度,我们结合工程设计编制了《单心双曲拱坝形体设计程序》,工程实践表明,100余米高的拱坝,只要算1个小时,就可以把分19个坝段横向缝、分块方量、开挖坐标及各
I. INTRODUCTION After the selection of double-curvature arch dam, subsequent designs often encounter geometry calculation, such as: seam calculation, block calculation, excavation coordinate calculation, body calculation of each elevation arch and so on. Due to the artificial factors, there is a reasonable solution to the problem of seam division. We have carried out a preliminary analysis based on a project design, and put forward that taking the center line of each elevation arch and the radial direction of the arch It is obvious that the shape calculation of double-curvature arch dam is not only heavy workload, but also easy to make mistakes. In order to improve the design quality and speed up the design progress, we combine Engineering design compiled a single heart double curvature arch body design program, engineering practice shows that more than 100 meters high arch dam, as long as 1 hour, you can divide the 19 dam horizontal joints, Excavation coordinates and each
