泡沫轻质土在道路工程中的应用

Application of Foam Light Soil in Road Engineering

在沿海工程施工中常常会遇到软土地基,它一方面会影响整体施工效率和质量,另一方面会对整体的施工进度造成不利影响。在传统工程项目施工过程中,常常会采用桩基法、换土法、灌浆法、排水固结等方式来加固地基,以保证施工正常进行。泡沫轻质土具有单位质量轻、流动性大、固结硬化后整体稳定性好及施工操作简便等特性,被广泛应用于桥梁台背回填、道路扩建、公路软土地基填筑等工程领域。本研究详细分析了泡沫轻质土的特性和泡沫轻质土的配合比试验,并探讨了其在道路工程中的应用情况。

Soft soil foundation is often encountered in coastal engineering construction. On the one hand, it will affect the overall construction efficiency and quality, on the other hand, it will have an adverse impact on the overall construction progress. In the construction process of traditional engineering projects, pile foundation method, soil replacement method, grouting method, drainage consolidation and other methods are often used to strengthen the foundation to ensure the normal construction. The lightweight foamed soil has the characteristics of light weight, large fluidity, stable integrity after consolidation and hardening, and simple construction operation. It is widely used in engineering fields such as bridge abutment backfill, road expansion, road soft soil foundation filling and so on. In this study, the characteristics of foamed lightweight soil and the mix proportion test of foamed lightweight soil are analyzed in detail, and its application in road engineering is discussed.
