基础换填在堤防工程中的应用

Foundation Replacement Applied in the Dam Project

在堤防工程施工中,因淤泥层的地基承载力很低,无法满足设计要求,为此通过对软基特性和工程实况等方面的综合分析,选用基础换填块石方法对软基进行处理。换填基础的设计必须满足基底应力和抗滑稳定要求,并在施工过程中按既定施工组织方案有序实施。实践证明,该方法技术可行、操作便利,施工效果理想,值得参考应用。

In the construction of dike project, the silt layer foundation bearing capacity is too weak to meet the requirement of design. According to a comprehensive analysis of soft soil characteristics and project actual status, this paper advises to handle soft foundation by replacing foundation with stones. Replacement foundation design must satisfy the base stress and anti sliding stability requirements, and the established construction organization plan should be implemented in the construction process. Practice has proved that this method is technologically feasible. As the operation is convenient and construction effect is ideal, it deserves reference application.
