泡沫轻质土在桥梁台后地基处理中的应用

Application of Foam Light Soil in Treatment of Bridge Abutment Foundation

长三角地区河涌密集,软土地基分布广泛,桥头路基沉降引起的桥头跳车成了普遍性的桥梁工程病害。近年来,作为新技术的泡沫轻质土技术逐渐应用于土木工程各领域的建设中,而引入泡沫轻质土进行桥头路基处理,成为缓解桥头跳车现象的一个新方向。针对泡沫轻质土在宁波市解放桥拓宽工程台后地基处理中的施工应用进行拓展阐述。

The rivers are dense and the soft soil foundations are widely distributed in Yangtze River Delta.The bridgehead bump caused by the roadbed settlement of bridgehead becomes the common fault of bridge engineering. In recent years, the foam light soil technique, as the new technology, is gradually applied in the construction of civil engineering field. And the introduction of foam light soil to treat the bridgehead roadbed becomes a new direction to alleviate the phenomenon of bridgehead bump. The article expands and sets forth the construction application of foam light soil in treatment of bridge abutment foundation of Ningbo Jiefang Bridge Widening Project.
