强夯法在变电站地基处理中的应用

The application of dynamic consolidation in foundation treatment in transformer substation

通过工程实例对强夯法加固湿陷性黄土地基进行了分析,从设计过程、施工工艺等方面进行了论述,提出了强夯法是设备和工艺简单、经济易行、工效高的地基处理方法,进行了试夯前后的常规物理力学性能的研究,达到了4 m以内湿陷性全部消除的效果,解决了大面积换土工期长、造价高的问题。

Strengthening collapsible loess foundation using dynamic consolidation based on engineering practice was analyzed, the design process and construction technology were discussed, and pointed out that dynamic consolidation is a foundation treatment method with simple equipment and technology, eocncxny and high efficiency. The common physical mechanical properties before and after trial ramming were studied, the effect of eliminating loess collapse in 4 meters was reached, and solved the problem of long construction period and high cost of large soil replacement.
