【摘要】：在我国西电东送的发展战略中，南部通道主要由贵州、云南火电厂及两省交界处水电厂的电能资源向广东方面输送。贵州省煤矿资源丰富，主要通过火力发电厂发电，大量燃煤产生的粉煤灰已经引起了严重的环境污染，电厂为处置粉煤灰花费大量资金征地并建设贮存场，粉煤灰堆积不仅造成土地资源占用、破坏原地面土质等恶劣影响，还影响到当地群众的正常生活，严重的地区危及人体健康。贵州高速公路建设为粉煤灰处理问题提供了新的途径，可以有效大量消耗粉煤灰，提升粉煤灰的利用率。本文依托《贵州高速公路粉煤灰筑路综合利用技术研究》对粉煤灰作筑路材料进行研究，计算粉煤灰路堤、石灰粉煤灰稳定碎石基层以及粉煤灰水泥混凝土路面三类掺粉煤灰的道路结构层的预算定额，为贵州省同类型工程采用粉煤灰做筑路材料时提供参考。主要研究内容如下： ①实地收集贵州5个电厂的粉煤灰样品，通过试验研究总结每种粉煤灰的物理性质、化学性质及工程性能； ②分别提出粉煤灰典型路堤结构组成形式、石灰粉煤灰稳定碎石基层结构、粉煤灰水泥混凝土路面结构，通过试验研究得出粉煤灰结构层的最佳配合比，，分析每种结构层的路用性能和施工工艺等； ③根据施工现场调查得到人、机、料的实际消耗数据，按照现行规范规定的预算定额编制办法及公路工程预算定额等相关规范，补充编制完成《贵州省高速公路利用粉煤灰筑路相关定额》； ④综合分析粉煤灰筑路材料施工技术及定额研究的意义，从社会人文、环境污染以及用粉煤灰为电厂和工程建设带来的经济价值几个方面进行分析。本文对贵州省5个电厂生产的粉煤灰在公路建设方面的应用展开研究，力求证明在公路建设上采用粉煤灰作筑路材料切实可行，不但可以解决粉煤灰对社会环境及工业发展带来的负面影响，而且从一定程度上可以起到降低公路建设成本的作用，对贵州省经济发展及交通建设两方面都非常有利。
[Abstract]:In the development strategy of power transmission from west to east in China, the southern corridor is mainly transported to Guangdong by the power resources of Guizhou, Yunnan thermal power plants and hydropower plants at the junction of the two provinces. Guizhou is rich in coal resources, mainly through coal-fired power plants, a large number of coal-fired coal ash has caused serious environmental pollution, power plants spend a lot of money to dispose of fly ash land requisition and construction of storage sites. The accumulation of fly ash not only results in the occupation of land resources, but also affects the normal life of local people and endangers human health in serious areas. The construction of Guizhou expressway provides a new way to deal with the problem of fly ash, which can effectively consume fly ash and improve the utilization ratio of fly ash. Based on the comprehensive utilization technology of fly ash in Guizhou Expressway, this paper studies fly ash as road building material, and calculates the flyash embankment. The budget quota of lime fly ash stabilized crushed stone base and fly ash cement concrete pavement three kinds of road structure layer mixed with fly ash provides a reference for the use of fly ash as road construction material in the same type of engineering in Guizhou province. The main contents of the study are as follows: 1 collect fly ash samples from 5 power plants in Guizhou, and summarize the physical, chemical and engineering properties of each kind of fly ash through experimental study; 2 respectively put forward the typical structure form of fly ash embankment, lime fly ash stabilized crushed stone base structure, fly ash cement concrete pavement structure, get the best mix ratio of fly ash structure layer through the test research, The road performance and construction technology of each structure layer are analyzed. 3According to the actual data of human, machine and material consumption obtained from the site investigation of construction, and according to the method of compiling budget quota and highway engineering budget quota, and so on, Completion of supplementary compilation of "Guizhou Province highway using fly ash road building related quota"; (4) the significance of construction technology and quota research of fly ash road construction material is analyzed synthetically. The social humanities, environmental pollution and the economic value brought by using fly ash for power plant and engineering construction are analyzed. In this paper, the application of fly ash produced in 5 power plants in Guizhou Province in highway construction is studied, and it is proved that it is feasible to use fly ash as road material in highway construction. It can not only solve the negative impact of fly ash on social environment and industrial development, but also reduce the cost of highway construction to a certain extent, which is very beneficial to the economic development and traffic construction of Guizhou Province.
