轻质泡沫混凝土在傍河路堤拓宽工程中的应用

摘要

分析了傍河路堤拓宽技术存在的难点，结合浙江某县道非机动车道拓宽工程，从经济性与合理性两个角度，采取了轻质泡沫混凝土代替局部回填土的方案，并简单介绍了该方案的施工技术，工程实践表明，轻质泡沫混凝土方案不仅能满足路堤拓宽的要求，还能满足生态建设的理念。%Analyzed the technical difficulties in existing embankment widening engineering nearby the river,combined with the widening em-bankment engineering of a avenue in Zhejiang province,starting from two aspects of economy and rationality. Scheme of using lightweight foam concrete to replace the back-fill are applied in the embankment engineering. Construction process is simply introduced. Engineering application show that this scheme satisfies not only the requirement of embankment widening engineering but also the concept of ecological construction.
