滨海电厂复杂地基处理方案研究

Disquisition for Complicated Groundwork Treatment Scheme of Seaside Fossil Power Plant

华能威海电厂三期扩建工程主要利用老厂灰场进行建设,冲填土(粉煤灰)层较深,本着技术可靠、经济合理、满足施工进度的原则,根据其上建(构)筑物对地基的不同要求;整个厂区的地基处理分别采用了超挖换填、钻孔灌注桩、粉喷桩等几种不同的方案。重点介绍该工程地基处理方案的选择和优化,可供同类工程地基础处理参考。

Huaneng Weihai fossil power plant The Phase III sites on the original ash yard area. Alluvial soil （fly ash） layer is too thick. Based on the different requirements of the superstructure, to meet technical security, appropriate cost and construction schedule, the overexcavate replacement, borehole cast-in-place concrete pile and cement grouted pile are used in the groundwork treatment scheme. This article focuses on the selection and optimization of groundwork treatment scheme. The experience in this project could be reference for other approximate projects.
