某烧结主厂房深层强夯置换复合地基处理

Composite foundation treatment of a main sintering plant with deep dynamic compaction replacement

在某烧结工程中,采用了深层强夯置换复合地基处理,利用现场的高炉钢渣作填料,强夯成钢渣桩与周围地基土共同承担基础荷载的复合地基。比传统的强夯地基处理深度更深,能改善深层的软弱下卧层土的工程特性;就地取材,变废为宝,既解决了钢渣的转运堆放问题,又降低了工程造价。

In a sintering project,a deep dynamic compaction replacement meth- od of composite treatment was adopted, and the blast furnace slag on site was used as filling material, it was compacted deeply into steel slag pile, which bears the founda- tion load of the composite foundation mutually with the surrounding foundation soil. The dynamic compaction foundation treatment depth treated with this method is deeper than the traditional foundation treatment depth, and the engineering properties of weak soils in deep layer can be improved;Using local materials and recycling wastes not only solves the transferring and stacking problems of steel slag, but also re- duces the engineering cost.
