摘　　要：边坡防护作为基坑放坡的关键环节。传统边坡多以混凝土喷锚的形式进行防护,但在雨季时期处在膨胀土地区的边坡防护质量难以得到有效保证。针对此问题,以南宁国际空港综合交通枢纽工程为例,对装配式防护体系在膨胀土地区的应用进行探索和研究。通过理论和工程实际相结合,阐述该防护体系结构形式、安装及拆除关键技术。研究表明,该装配式防护体系能有效应用在膨胀土地区,既能保证工程工期,又可实现绿色施工,在一定程度上充分体现了装配式面层可装配性、施工高效性的特点。Slope protection is the key link of foundation excavation slope release. The traditional slope protection is mainly carried out in the form of shotcrete anchor, but it is difficult to guarantee the quality of slope protection in expansive land area in rainy season. Aiming at this problem, Nanning International Airport comprehensive transportation hub project is taken as an example to explore and study the application of prefabricated protection system in expansive land area. Through the combination of theory and engineering practice, the structural form of this protection system and the key technology of construction, installation and removal are described. The research shows that the prefabricated protection system can be effectively applied in the expansive soil area, which can not only ensure the construction period, but also achieve green construction. To a certain extent, it fully embodies the characteristics of the prefabricated surface layer prefabricated and construction efficiency.
