Restorative Research of Stone Arch Bridge in River Kotsuki

竹桥大桥桥修复图研究项目摘要建于1848年，1994年8月6日被暴雨冲毁.我们勘察了这座由大石头组成的桥，并参照130年前的老照片绘制了修复图。作为检查的结果，竹桥的桥在桥的末端重建得比原来的桥高。在拱桥的中央，铺设的石块是为了保持水平水平。那是90年前的事了。通过使用混凝土，桥上的铺装路面达到了更水平的水平，以便开车。1994年被毁的竹野桥石拱桥和新坎桥大桥的研究项目概要。1997年的研究报告。这些拱形石桥是由…组成的更多的拱形石圈。结果，拱形石桥不是圆形的，而是因为草木川河流的猛烈水流向上移动到拱形石桥表面而变得像鸡蛋一样。我们对被破坏的石桥进行了调查，并写了几张图纸，以便将拱形石桥与被破坏的石桥进行比较。研究报告摘要：我们于1997年修复了西石桥的拱形石桥。为了修复西石桥的拱形石桥，我们进行了一年的勘察，发现了原来的坡度。我们的检查结果是，西桥的桥被重建得像竹桥桥一样，在桥端的高度比桥的桥高。在拱形石桥的中心，为了保持水平水平，铺装的石头是例外的。一百年前，重建拱形石桥的技术人员的工程技术非常好，但最近逐渐下降。西大桥桥由四个连续的圆组成，是日本最著名的桥。据推测，修复后的石桥-原桥长315米-180公里(日语中的长度)。较少

Abstracts of research project for restoration drawing of bridge of TakenohashiBridge of Takenohashi was built in 1848 and was destroyed by heavy rain in 1994 on August 6 th. We surveyed the bridge consisted of big stone and drawed its restoration drawing on reference to the old photograph one hundred thirty years ago. As a resul of the examination, bridge of Takenohashi was reconstructed higher on the end of the bridge than the original bridge in its height. On the center of the arched bridge the paved stones were excepted in oder to maintain the horizontal level. It was ninty years ago.By the use of concrete, the surface of the paved road in the bridge was reached more horizontol level in order to drive cars. Concrete was used thin in height toward the center of the bridge.The outline of research project for the arched stone bridge of Takenohashi and bridge of Shinkanbashi that were destroyed in 1994.The reseach report was examined in 1997. These arched stone bridges were consisted of … More arched stonre circle. As a result, the dertroyed stone bridge was not round, but was changed like an egg in shape because the violent current force of river-River of Kotsukigawa moved up to the surface of the arched stone bridge. We surveyed the destroyed stone bridges and wrote several drawings in order to compare the arched stone bridge with the destroyed stone bridge.Abstract of research report that we restorated the arched stone bridge-bridge of Nishidabashi in 1997.The arched stone bridge was built in 1846. We surveyed it for one year to restorate the arched stone bridge-bridge of Nishidabashi and found the original slope. As a result of our examination, bridge of Nishidabashi was reconstructed like bridge of Takenohashi higher on the end of the bridge than the oniginal bridge in height. In the center of the arched stone bridge, the paved stones were excepted in order to maintain the horizontal level. The engineering of technical men who reconstructed the arched stone bridge was very good one hundred years ago but recently droped gradually. Bridge of Nishidahashi is consisted of four successive circle which is the most famous in Japan. It was guessed that the restorated stone bridge-original bridge was 315 meters-one hundred eighty Ken (Japanese word in length). Less
