伴随国民经济快速发展,公路网络不断延伸,在生产经营活动中发挥着重要作用,对其施工质量也提出了更高的要求。路基作为公路工程的关键构成部分,其承载能力直接影响了车辆行驶的安全性,必须结合实际地质条件,选取相应的施工技术,提高路基结构的稳定性。本文主要对粉煤灰路基填筑技术进行研究分析,并探寻质量控制的有效措施,以期为公路工程建设提供理论性指导。 With the rapid development of the national economy, the highway network has been continuously extended, playing an important role in the production and operation activities and putting forward higher requirements on the quality of its construction. Subgrade as a key component of highway engineering, its bearing capacity has a direct impact on the safety of vehicle driving. It must be combined with the actual geological conditions to select the appropriate construction technology to improve the stability of subgrade structure. In this paper, the research and analysis of fly ash subgrade filling technology is mainly carried out and the effective measures of quality control are explored in order to provide theoretical guidance for highway construction.
