燃煤发电厂深填沟区地基处理方案分析与实践

The analysis and practice on foundation treatment for extra-high fill at coal-fired power plant

针对某燃煤发电厂深填沟区地基处理,通过认真分析场地地质条件参数,对不同性质、类别的建(构)筑物,按基础荷载大小及其功能和重要性,对地基承载力和变形的不同要求,提出了多种地基处理方案,如钻孔灌注桩、强夯、孔内深层强夯灰土桩、振冲碎石桩等,并对各方案进行分析比选,最终推荐合理的地基处理方案,使地基处理做到安全适用,经济合理,为以后地震区深填沟区地基的处理提供一些工程经验。

Based on the extra-high fill site at a coal-fired power plant, the five foundation treatment method, such as driven cast-in-place pile, precast pile, rammed ground, compacted soil-lime columns and gravel columns etc. , is analysed and compared. The viable and rational founda-tion treatment method is recommended and designed, in order to offer some experience for foundation treatment for the extra-high fill site.
