【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。
[Abstract]:China is one of the countries rich in natural stone, which has a special position in the global natural stone species. The natural stone is used in the construction of the barge beside the garden water body, which makes it an indispensable element in the garden water body. Natural stone is a kind of material with aesthetic value. It is the purest material in balance with human ecology. It is the original material of the earth like plants and wood. It has no large amount of organic residues and no modern industrial pollutants. Natural stone comes from rock and mine and belongs to non-renewable resource. We should develop it reasonably and utilize it correctly. However, with the development of garden industry in China, the demand for stone materials is increasing day by day, and the resources of Taihu Lake stone have been exhausted. It is a new challenge for garden engineering to excavate, evaluate and apply new stone materials. In this paper, the evaluation standard of natural stone for barge is established from four aspects: ornamental, weathering resistance, safety and scale. The species, distribution and quantity of natural stone in Zhangjiajie in Wuling Mountain area were investigated. Although the beautiful outline of Taihu stone is loved by people, with the development of garden construction, the resources of Taihu stone are exhausted day by day. In this paper, the natural stone material and Taihu stone, granite are viewed from the view of Zhangjiajie. The weathering resistance and safety are compared to evaluate whether the natural stone in Wuling Mountain area is suitable for garden barge engineering. The main conclusions of this paper are as follows: (1) the evaluation standard of natural stone material in the barge of garden water body is established from four aspects: ornamental property, weathering resistance, safety and scale. (2) the evaluation and analysis of landscape effect of different application forms of natural stone in the barge of garden water body show that the stone of Taihu Lake has "good" landscape effect in the application of Yuyuan garden, which is suitable for rockery; The natural stone of Zhangjiajie has good landscape effect in the application of Jinbian River in Zhangjiajie National Forest Park. 3 the engineering study of natural stone shows that the weathering resistance of granite and Zhangjiajie sandstone is good, the weathering ability of Taihu stone and Zhangjiajie limestone is general, and Taihu stone and limestone have similar physical and chemical characteristics. By Y energy spectrum analysis, the natural radioactivity of 232Th226Ra and 40K of Taihu stone, limestone, sandstone and granite are all significantly different, and the internal and external radiation values are in line with the national standard.
