摘要

为适应坝内水位升高变化及提高防洪标准、对堤坝进行加宽改造，新加宽部分会引发堤坝的工后不均匀沉降和地基侧向位移、对其稳定性产生影响。采用有限元方法，分析了加宽宽度、地基处理、土工格栅性能及铺设方式对加宽堤坝工程性能的影响。由计算结果可见通过上述方法可提高加宽堤坝的稳定性、减小工后沉降和侧向位移。相应结论可供类似工程参考。

Abstract

To fit the water level rise and improve the flood control standard

the dam usually is widened. New widening part of the dam can induce the nonuniform post-construction settlements and lateral displacements

which will influence its stability. The finite element method is used to analyze the influences of the widening width

ground treatment

geogrid’s character and layout manner on the project character of the dam. The calculation results show that by the above means

the stability of the dam can be improved; and the post-construction settlements and lateral displacements can be decreased. The conclusions can be for reference to similar projects.
