【摘要】 我国是天然石材非常丰富的国家之一,在全球天然石材种类中具有特殊的地位。而园林水体边的驳岸建设基本采用天然石材,使其成为园林水体中一个不可缺少的重要元素。天然石材是一种具有美学价值的材料,是与人类生态相平衡的最纯净的物质,与植物、木头一样为地球的原生物质,它没有大量有机残留物质,也没有现代化工业污染物。天然石材来源于岩石、矿山,属于不可再生资源,我们应该合理开发、正确利用石材资源。但随着我国园林事业的发展,对石材的需求量在日益增加,而太湖石的资源已耗用殆尽,挖掘、评价和应用新的石材,是园林工程面临的新的挑战。本文从观赏性、抗风化性、安全性、规模性四个方面建立评价驳岸天然石材的标准。对武陵山片区的张家界天然石材种类、分布、数量进行调查研究。虽然太湖石优美的外形轮廓深受人们的喜爱,但随着园林建设的发展,太湖石资源日渐枯竭,本文将张家界天然石材与太湖石、花岗岩从观赏性、抗风化性及安全性方面进行比较,评价武陵山片区天然石材是否适合做园林驳岸工程的材料。论文的主要结论包括以下3个方面：1从观赏性、抗风化性、安全性、规模性四个方面建立园林水体驳岸天然石材的评价标准。2天然石材在园林水体驳岸中不同应用形式的景观效果评价分析表明：太湖石在豫园运用中具有“好”的景观效果,适合做假山；张家界天然石材在张家界国家森林公园金鞭溪应用中具有“好”的景观效果,适合做驳岸材料。3天然石材的工程性研究表明：花岗岩与张家界砂岩的抗风化能力好,太湖石与张家界石灰岩抗风化能力一般,并且太湖石与石灰岩具有相似的物理化学特征。通过Y能谱分析,太湖石、灰岩、砂岩、花岗岩的232Th、226Ra和40K的天然放射性比活度都达到显著性差异水平,其内照射与外照射值符合国家标准。更多还原

【Abstract】 China is one of countries with rich natural stone, which has a special position in the global natural stone species. The revetment had been constructed with natural stone,Make it become an important element of an indispensable garden in water. Natural stone is a kind of aesthetic value of material, is the most pure material balance and human ecology, and plant, wood as the primary materials of the earth, it is not a large amount of organic residues, no modern industrial pollutants. In the rock, mining source of natural stone, belonging to non-renewable resources, we should rationally develop, the correct use of stone resources. But with the development of the landscape industry in our country, the demand for stone is on the increase, while Taihu stone resources have been drained, mining, evaluation and application of new material, new challenges facing the garden project.This paper from the view, weathering resistance, the security, the scale of four aspects of the establishment of the evaluation standard of natural stone revetment. Zhangjiajie natural stone species, distribution, quantity of investigation and study. Although Taihu stone beautiful shape people’s favorite, but along with the development of landscape construction, Taihu stone resources exhaustion, this article will Zhangjiajie natural stone and Taihu stone, granite are compared from the ornamental, weathering resistance and security, evaluation of Wuling mountain area natural stone is suitable for garden revetment engineering materials. The main conclusions of this paper include the following3aspects:1from the view, weathering resistance, the security, the scale of four aspects of the establishment of landscape water revetment natural stone assessment standard.2natural stone in the garden water revetment in evaluation of different application forms of landscape effect analysis shows:Taihu stone has a "good" effect of the landscape in Yu Garden use, suitable for rockery; pebble with "good" effect of the landscape in the Zhangjiajie national Forest Park applications, suitable for revetment material.3Study on engineering of natural stone show:Granite and sandstone weathering resistance and good, Taihu stone and limestone weathering ability in general, and Taihu stone and limestone with physical and chemical characteristics similar to the. The gamma energy spectrum analysis, the natural radioactivity of Taihu stone, limestone, sandstone, granite232Th,226Ra and40K have reached significant difference level, the irradiation and external irradiation value in line with national standards.更多还原
