视线设计主要包括:一、地面坡度问题;二、视距问题;三、视线角度问题。本文就地面坡度问题作一初步分析。 地面坡度的大小与以下因素有关(图1):1.首排观众眼睛到设计视点的距离,简称起始距离,即a值。2.首排观众眼睛到设计视点的高度,简称起始高度,即b值。3.观众眼睛到头顶的高度,简称升起值,即c值。4.观众席椅背到椅背的距离,即排距或升起段长度,即d值。
The line-of-sight design mainly includes: 1. Ground slope problem; 2. Line-of-sight problem; 3. Line-of-sight problem. This article makes a preliminary analysis of the ground slope problem. The size of the ground slope is related to the following factors (Fig. 1): 1. The distance from the first row of viewers’ eyes to the design viewpoint, referred to as the initial distance, that is, a value. 2. The height of the first row of viewers’ eyes to the design viewpoint, referred to as the initial height, ie, b value. 3. The height of the viewer’s eye to the top of the head, referred to as the rising value, that is, the c value. 4. The distance from the back of the auditorium chair to the back of the chair, ie the length of the row or raised section, ie the d value.
