摘要

摘要本文介绍了轮胎橡胶替代骨料在混凝土坝施工中的性能和效益。使用轮胎橡胶的目的是尽量减少传统骨料材料的数量，并有助于减轻黎巴嫩的固体废物问题。利用黎巴嫩Janna大坝的数据进行了全尺寸试验和分析。第一组与结构和地震分析相关的模拟对使用传统骨料混合物的混凝土大坝进行了分析，以定义参考大坝设计方案。提出了第二组模拟，使用轮胎橡胶骨料来定义混凝土大坝建设的第二种情况。两种方案之间的比较表明，在大坝建设的混凝土混合料中引入轮胎橡胶作为骨料显示了其性能，并在减少传统骨料体积和在自然界中随意处置轮胎方面提供了好处。

Performance and benefits of tire rubber as substitute aggregates in the construction of concrete dams

ABSTRACT This paper presents the performance and benefits of tyre rubber as substitute aggregates in the construction of concrete dams. The use of tyre rubber aims at minimising the quantities of traditional aggregate materials, and contributes in mitigating the solid waste problem in Lebanon. Full scale experiments and analyses were performed using data of Janna Dam (Lebanon). A first set of simulations related to structural and seismic analysis were carried out for concrete dams using traditional aggregate mixture to define a reference dam design scenario. A second set of simulations were proposed using tyre rubber aggregates to define a second scenario for the construction of the concrete dam. A comparison between the two scenarios shows that the introduction of tyre rubber as aggregates in the concrete mixture for the construction of the dam showed its performance and provides benefits in terms of reduction of traditional aggregates volume and of random disposal of tyre in the nature.

期刊介绍： Geomechanics is concerned with the application of the principle of mechanics to earth-materials (namely geo-material). Geoengineering covers a wide range of engineering disciplines related to geo-materials, such as foundation engineering, slope engineering, tunnelling, rock engineering, engineering geology and geo-environmental engineering. Geomechanics and Geoengineering is a major publication channel for research in the areas of soil and rock mechanics, geotechnical and geological engineering, engineering geology, geo-environmental engineering and all geo-material related engineering and science disciplines. The Journal provides an international forum for the exchange of innovative ideas, especially between researchers in Asia and the rest of the world.
