摘　　要：以台州湾大桥及接线工程部分路段路基工程为背景,从原材料、浇筑、养护和质量控制等方面提出了一种适用于滨海软土地区路基泡沫混凝土填筑施工技术,并通过数值模拟分析泡沫混凝土路基沉降。结果表明:泡沫混凝土路基工后沉降比传统填筑路基减少11.3%,该技术效果良好,适用于滨海软土区路基工程。Depending on the subgrade engineering in some sections of Taizhou Bay Bridge and the connecting works,a construction technology applicable for foam concrete filling of subgrade in coastal soft soil area,involving raw material,pouring,maintenance and quality control,was proposed,moreover,the subgrade settlement was analyzed by means of numerical simulation.The result shows that the post construction settlement of foam concrete subgrade has a 11.3%drop than that of traditional filling subgrade.This technology has good effect and is applicable for subgrade engineering in coastal soft soil area.
