生态混凝土护坡的构建技术及生态效应评价.docVIP

东南大学学士学位论文 PAGE PAGE IV 生态混凝土护坡的构建技术及生态效应评价 摘 要 人类进行边坡防护已有很长的历史，但在防护与绿化美化两方面一直没有统一，与传统防护材料相比，生态混凝土既有较高的强度能有效地进行边坡防护、加强边坡的稳定性，提高防护年限，又具有很大的孔隙率便于植物在其中生长，具有改善环境的功能，是一种被广泛认可的生态修复材料，因此，开展生态混凝土的研究具有重要意义。 本文主要针对具有生态环保功能的生态混凝土的配合比设计、强度、干湿交替作用下的耐久性、护坡构建和综合生态效应等方面进行了探讨和研究。在基本性能方面，本论文研究了生态混凝土在掺加矿物掺合料时，其强度随着掺合料掺量的变化规律。除此以外，还研究了掺加矿渣的生态混凝土处在干湿交替作用下的耐久性特点，进行了生态混凝土抗干湿交替性能的试验。在护坡构建中，还研究了植物必要的生长环境、生态护坡植物的选择以及生态护坡基质的选择。此外，本文最后研究了不同粗骨料的生态混凝土水质净化性能和污水处理的标准。 关键词：生态混凝土，干湿交替，生态护坡，强度，水质净化 slope protection technology by ecotype porous concrete and ecological effects evaluation Abstract The side slope defence has been a continuous career for human beings.However,a perfect junction has never been found between the side slope defence and virescence.Compared with the traditional defence materials,ecotype porous concrete can not only attain a higher strength to efectively defend the side slope and reinforce its stability in a longer defense period,but also get a higher void ratio to make it possible for plants to grow better in it. It really functions in improving the environment and has been commonly considered as an ecological concrete. Therefore,to do researches on ecotype porous concrete is a significant task. Themix proportions,strength,wet-dry circle,building the side slope defence and Eco-environmental security of ecotype porous concrete have been studied abundantly in the paper. While the change of compressive strength with silica fumes, fly ash and slag also have been studied.Besides,the wet-dry cycle resistance property of ecotype porous concrete has also been studied.Construction of the berm, a major study of the necessary growth environment, ecology slope of the choice of slope protection and ecological matrix choice.In the last chapter, the main test is water purification and sewage treatment standards.
