泡沫轻质土在纱帽枢纽工程中的应用研究

Applied Research of Foamed Lightweight Concrete in Shamao Pivotal Project

泡沫轻质土作为一种新型的环保工程材料,在公路桥梁台背回填、复杂地质条件下的边坡护理、道路加宽、路基填筑、软地基处理等工程中被广泛应用,使得新老路基的沉降不均、桥头跳车等安全问题得到了良好的解决。论文制备出了高性能泡沫轻质土,系统分析了其耐久性能,并在纱帽枢纽工程中进行了成功应用。

As a new type of environmental protection engineering material,foamed lightweight concrete was widely used in highway bridge abutment backfill,slope protection under complicated geological conditions,road widening,roadbed filling and soft foundation treatment,etc,the safety problems such as uneven settlement of new and old roadbed and vehicle bump at bridge head were well solved.In this paper,high performance foamed lightweight concrete was prepared,its durability was analyzed systematically,and it was successfully applied in the key project of Shamao.
