时值中国建筑科学研究院建筑机械化研究所成立三十周年之际,在此发表祝辞,本人至感荣幸。水坝、河堤或铁路、道路、通讯设施、高层建筑等社会资本的充实,是国民经济发展及民生稳定所必不可少的。但是,过去我们完全依靠人力和畜力作为这些的施工手段,即使在日本,甚至在数十年前还继续着这种状态,那时公共事业的进展确实缓慢。然而,第二次世界大战后,日本由于积极地引进推土机、挖土机等现代建筑机械来代替传统的人力、畜力,以谋求实现建筑机械化,所以能够从治山、治水、开发电力等公共事业入手,高效能地 At the time of the 30th anniversary of the founding of the Institute of Construction Mechanization of the Chinese Academy of Building Research, I would like to express my gratitude here. The enrichment of social capital such as dams, embankments or railways, roads, communication facilities, and high-rise buildings is indispensable for the development of the national economy and the stability of the people’s livelihood. However, in the past, we completely depended on human and animal power as the means of construction. Even in Japan, even in the state that continued even decades ago, the progress of public utilities was indeed slow. However, after the Second World War, Japan actively replaced bulldozers and animal husbandry with modern construction machinery such as bulldozers and excavators to seek the realization of construction mechanization. Therefore, Japan can start with public utilities such as controlling mountains, controlling water, and developing electricity. Highly efficient
