| 摘 要： | 吹填造陆是沿海地区粉煤灰利用的主要途径之一,粉煤灰吹填区地基的土质颗粒细腻、松散,承载力差,必须经过加固处理后方可使用。以在粉煤灰吹填区内建设的某大型市政工程为例,根据吹填区的地形、工程地质条件提出具体施工技术要求和加固施工方案,分别采用桩基和强夯法对主体结构物下和场内道路范围内的地基进行加固处理,现场施工效果表明,用该方法加固处理滨海粉煤灰吹填地基具有可行性。

| Abstract: | Fly-ash can be used for land reclamation in the coastal region. Because of super fine and loose soil granule and low bearing capacity in the fly-ash reclaimed area, the foundation must be reinforced before construction. By combining with one large-scale municipal project that is constructed in fly-ash reclaimed area, construction technique requirements and reinforcement scheme are proposed in detail based on the relevant geologic and topographic conditions. Pile foundation method is used to reinforce main structure base, and dynamic compaction method for site road base. The construction result certifies the feasibility of the above reinforcement methods. |
