摘要：我国阅渐地区的本拱廊桥有着极高的关学与建筑价值.但诸多靠例证实，洪涝灾害对于木质拱桥的破坏十分严重，此对浙西南山区支建筑本拱席桥进行了研究，从遗型及结构角度出发，探完古代工匠在支床桥防洪系块上的建筑智慧，并通过本拱诉桥毁于洪灾的典型案例，分新本质拱桥在洪涝灾害作用下的碳坏机理提出具有泄洪系统的古建筑确桥的技术方案，不仗可以有效地起到泄洪的作用，而且可以减小对风的阻力，提高整个顾桥的稳定
性，同时可以收集雨水，天气炎热时雨水蒸发吸热，起到降低温度的作用。关键词：本拱康桥：洪灾：泄洪系统：保护

Abstract: China has a history of thousands of years. Many buildings left over by history have extremely high aesthetic and architectural values. The timber arch lounge bridge in Fujian and Zhejiang is one of the representatives. The ancients used their intelligence to build arch bridges over rivers with wood. At the same time, a promenade was built on the bridge. The number of lounge bridges in China is the largest in the world, and its preservation is relatively complete. However, many cases prove that the damage of flood to timber arch lounge bridge is serious. The paper studies ancient wooden arch bridges in the mountainous areas of southwesterm Zhejiang, and explores the architectural wisdom of ancient craftsmen in flood con-trol by timber arch lounge bridges. It also analyzes the typical cases destroyed in floods and the failure mechanism of the
flood disaster. The technical ideas on protection and stability for timber arch lounge bridges are put forward. Key words: timer arch lounge bridge; flood; flood discharge system; bridge protection
山一水一廊桥，于山水之胜，深山清幽之所，
在绿树掩映之间，一座阁楼高耸的廊桥别其风姿、异彩纷呈.水为山之魂，水为桥之侣，桥下或碧水据褥，或深潭如镜，或猛浪奔岩，远远望去，犹如一幅蛟龙出水的优美画卷.廊桥是古人留给我们的宝贵财富，是我国古代人民智慧的重要体现然《管子度地篇》中说到“五害之中水为大”，史记中也提到“汤汤洪水天，浩浩怀山襄陵，下民其忧”，因此，

古桥及民俗建筑随工研究万方数据
从古至今，洪涝灾害对于我国的建筑及桥梁都有着极大的威胁
摊开历史的画卷，《清明上河图》中那座横跨汴水的虹桥，可以说是我们对古廊桥最清晰的记忆虹桥的建造工艺在北宋十分盛行，而后也随着宋朝的灭亡而混灭.但经科研人员调查与考证发现，编木虹桥的建造工艺在闽浙地区的木拱廊桥上得到了继承与发扬.虹桥与木拱廊桥均采用编木结构，梁穿插别压形成拱，从受力分析角度来看，这种结构趋于合理[2].这种将桥建于河岸之间，并在桥面加上廊屋，利用廊屋来保护桥体，并将二者融
