文章从道法自然的观点出发,指出为防止地震灾害不应一味地加强加固地基与构造物,与强大的自然力相对抗。顺应自然,以柔克刚有时会取得意想不到的效果。文章简要介绍了我国加筋土在治水工程中应用和发展的历史;指出用柔韧的纤维材料与土石材料结合的加筋土结构在地震灾害中表现出卓越的性状。介绍了日本阪神地震、美国北里奇地震、土耳其伊斯坦布尔地震、中美洲萨尔瓦多地震、以及我国台湾集-集地震、四川的汶川地震中一些加筋挡土墙、加筋边坡和加筋土桥台的震后调查。调查的结果表明,在近年来世界上发生的这些著名大地震中,柔性的加筋土结构物没有发生整体失稳的案例。同时也介绍了用EPS(聚苯乙烯板块)作为填料在地震中良好的表现。调查研究结果表明,土工合成材料具有轻质、柔韧、高强的特点,在地震中表现出优异的性能。
From the point of view of Taoism and Nature, the article points out that in order to prevent earthquakes, we should not blindly strengthen and reinforce foundations and structures and confront strong natural forces. Conforming to nature, Eruca has sometimes achieved unexpected results. This paper briefly introduces the history of the application and development of reinforced earth in water control projects in our country. It points out that the reinforced earth structure combined with flexible fiber materials and earth-rock materials shows excellent characters in earthquake disaster. This paper introduces some reinforced retaining walls, reinforced slopes and reinforced earth abutments in Japan from the Hanshin earthquake, the Northridge earthquake in the United States, the Istanbul earthquake in Turkey and the Salvadoran earthquake in Central America, as well as the Taiwan-Jiadian earthquake in Taiwan and the Wenchuan earthquake in Sichuan After the earthquake investigation. The survey results show that in these famous earthquakes that occurred in the world in recent years, there is no case of global instability in the reinforced reinforced earth structure. At the same time, EPS (polystyrene plate) is also introduced as a good performance in earthquakes. The survey results show that geosynthetics have the characteristics of light weight, flexibility and high strength, and show excellent performance in earthquakes.
