Brief Narrating of Design and Construction of Strengthening Soft Soil Foundation of Culvert by Sand-Gravel Cushion Method

在软土地基上修建桥涵结构时,通常需对软土地基进行加固处理,以提高地基承载力,而砂砾垫层法就是一种比较简便、经济、实用的处理方法。据此,参阅相关文献,总结并简述了采用砂砾垫层法加固桥涵软土地基的机理、设计与施工,希望能提供有价值的参考。

order to increase During building the culvert structure on soft soil foundation, usually it is requisite to strengthen it in beating capacity. Whereas the sand -gravel cushion method is just a simple and convenient, economic and practical treatments. So the paper consults correlative literatures, sums up and briefly narrates the mecha- nism of strengthening the soft soil foundation by sand -gravel cushion method, the design and construction.
