深厚淤泥层上大型综合型海堤地基处理分析

Treatment of large-scale integrated seawall foundation on deep silt layer

深厚软土地基有多种处理方法,根据工程地质条件和项目不同,作出针对性的选择尤为关键.除了软土工程特性外,稳定性、沉降、工期、造价、环境等都是选择因素,需要多方案比较后才能优选.以某大型综合型海堤地基处理为例,从软土工程特性入手,对其不同区域的堤段划分和主体结构地基处理进行了分析,同时提出了应用真空—联合堆载预压法的建议,对类似工程具有积极的指导作用.

There are a variety of methods to treat the soft soil foundation,which makes it crucial to make a particular choice according to the geological conditions and specific projects.In addition to soft soil project properties,stability,subsidence,schedule,cost,and the environment are all factors that require attention before a final decision.Based on the example of a large-scale integrated seawall foundation treatment,this paper starts from the soft soil project properties,and analyzes its embankment division in different regions and foundation treatment of the main structure.It also proposes the employment of vacuum-combined preloading method.
