项目摘要

The subjects of this study are to analyze the present condition of the pier design of urban bridges, to find the factor that restricts the design of the piers, and to create the new design of the piers.In 1994, the bridges of Sapporo, Muroran, Ohsaka, and Tokyo were observed.As a result, it was found that due to several specifications on the design of the structures in river, creative design of the piers of river bridges was impossible. And the articles of the specifications are mainly based on the experiences not theoretical matters.On the other hand, in the case of the piers of highway bridges, the design of the head of the piers and the detail design of draining pipes were pointed out as the problem to be solved.On the basis of these these remarks, the study of 1995 is concentrated to the creation of new design by computer graphics.The software used for this study was SIGMARRIS.It was first found that the software had enough function for the purpose of this study. Using this software, the problems pointed out in the former year were tried to be improved. Several pictures, in which the head of the pier is improved or not, and the drining pipe or not, were drawn and compared.Also the piers consisted from straight members were drawn as a new trial of pier design. In the pier design, V-letter and reverse V-letter piers are combined. These are thought to be new conception and will introduce new idea to the design of bridge piers.

本研究的课题是分析城市桥梁桥墩设计的现状，找出制约桥墩设计的因素，创造新的桥墩设计。1994年，札幌桥、室兰桥、大坂桥、东京桥被观测到。结果发现，由于河流中构筑物的设计规范较多，对河流桥梁桥墩进行创造性设计是不可能的。规范的文章主要是基于经验，而不是理论问题。另一方面，以公路桥桥墩为例，指出了桥头的设计和排水管道的详细设计是需要解决的问题。在这些评论的基础上，1995年的研究集中在计算机图形学的新设计创作上。本研究使用的软件为SIGMARRIS。首先发现该软件具有足够的功能，以达到本研究的目的。利用该软件，对上一年提出的问题进行了改进。绘制了墩头改造与不改造、饮水管改造与不改造的几幅图，并进行了对比。并绘制了由直杆组成的桥墩，作为桥墩设计的新尝试。在桥墩设计中，v字墩与反v字墩相结合。这些被认为是新的概念，将为桥墩的设计带来新的思路。
