斜栱营造虽未被官方营造法式记载，但其自宋辽广泛出现于殿堂实物后，历经金元明清而不衰，特别是在民间表现出了极强的生命力和创造力,是中国传统木构建筑特别是民间斗栱技术发展成就的突出代表之一。西南地区是斜栱营造的活跃区，现有遗存丰富，技术、艺术成就高，是斜栱整体营造成就中不可或缺的组成部分，研究价值突出。.本课题将从类型及演变，区划特征与技术传播，匠作与匠意三个方面对西南地区斜栱进行系统研究,以此展现西南斜栱发展的全貌及成就，弥补之前对这一营造活跃区研究的不足。研究在深化以往斜栱关注点的基础上开启了“区划及特征”、“技术传播”、“营造匠意”三个斜栱研究上的新视角；同时，本研究特别关注到斜栱作为区域宏观问题研究“切片”的价值以及斜栱营造中隐含的传统工匠对设计本体问题的深刻理解及智慧解答，后者还将对广泛出现的如“斜栱以装饰性著称”、“晚期结构意义丧失、装饰过度繁复”等简单定论予以纠正。

Although not explicitly mentioned in the official traditional building manuals, angled bracket-arms construction is found widely in the buildings from Liao Dynasty to Qing Dynasty, which shows great vitality and creativity in folk. angled bracket-arms construction is one of the characteristic features of Chinese traditional buildings, especially in the development of technologies of Dougong in folk. There is rich heritage of angled bracket-arms construction with great technical and artistic values in southwest China, which is an indispensable part of the overall achievement of angled bracket-arms construction..This topic is a systematic study includingseveral aspects as follows: the types and the evolution of angled bracket-arms, region division and features, technology dissemination, constructions and concepts.Firstly, the full picture and achievement of the development of angled bracket-arms in southwest China will be shown in order to cover the shortage of the research on this active area. Secondly, based on previous concerns, three new perspectives including “region division and features”, “technology dissemination” and “constructions and concepts” are provided. The more important thing is that the value of angled bracket-arms as a section of macroscopicopinions and the traditional craftsmen's deep understanding and wisdom on design are revealed, that would rectify the simple conclusions such as “angled bracket-arms is famous for decoration” and “Later, angled bracket-arms with excessive decorationis no longer a structural element”.
