一、横向缝距及其关系因素横向缝距是指双曲拱坝坝体中相邻两横向接缝之间的距离,通常以相邻两横缝间在坝顶面上,沿坝轴线的弧段长度表示之。这一缝距也称为该坝段的长度。但也有以坝顶上游面弧段长度表示的。在同一坝体中的各个坝段长度,有的相等,有的不等,因此,其缝距也有相等或不相等的情形。缝距尺寸的大小亦表示横问接缝布置的疏密程度。在布置坝体横问接缝时,应予考虑的关系因素甚多。其主要者:如坝址所在的地形条件,枢纽布置,坝内各水工管孔建筑物,
First, the horizontal gap and its relationship between the horizontal factor Tactile arch refers to the distance between two adjacent lateral joints in the dam, usually in the adjacent two transverse joints in the top of the dam along the dam axis Arc length of the said. This gap is also called the length of the dam. However, there is also the length of the upstream arc dam surface. In the same dam in the length of each dam, some equal, and some range, therefore, the same or not the same seam length. The size of the seam size also indicates the density of the seams. There are many factors that should be considered when arranging the seams for transverse seams. The main person: If the dam site where the terrain conditions, hub layout, the dam within the hydraulic pipe hole buildings,
