焦作电厂异地扩建工程地基处理方案比选
|
摘要
大中型火力发电厂主厂房对地基承载力要求较高,在天然地基不能满足要求的情况下,须进行地基处理。针对建构筑物荷载性质及分布不同,对应的地基处理方式也不一样,采用哪种地基处理方法更为经济、合理、有效,应进行具体分析。本文通过焦作电厂异地扩建工程实例,综合评价厂区主要建构筑物,有选择地采用700后注浆灌注桩、600后注浆灌注桩、CFG桩复合地基、天然地基等地基处理方式,对地基处理方案比选做了简要介绍。
The main workshop buildings of the large and medium thermal power plant have higher requirements for the foundation bearing capacity,if the natural foundation can not meet the requirements,the foundation must be treated. In view of the different building load characteristics and distribution of different architectural structures,corresponding method of foundation treatment is different also,then the more economical,reasonable and effective scheme of the foundation treatment must be adopted through analysis and comparison. By using the actual engineering example of Jiaozuo power plant offsite expansion project,comprehensively evaluating the main plant building structures,this paper has the option of using the post-grouting bored pile,CFG pile composite foundation and natural foundation etc. foundation treatment,the paper briefly introduces and analyzes the schemes of the foundation treatment.
