大型火力发电厂湿陷性黄土场地地基处理方案的优化

The Optimization of the Foundation Treatment Schemes of the Collapsible Loess Site of Large-scale Thermal Power Plant

通过在深厚严重的自重湿陷性黄土场地对某火力发电厂主要建筑物采用人工挖孔扩底桩和挤土夯扩钢筋混凝土大头桩两种地基处理方法的现场试验及分析比较,综合考虑安全、经济等多种因素,对可行的地基处理方法进行了论证和优化设计,以期为以后湿陷性黄土地区地基处理提供一些经验。

Through the field test and analytical comparison of two kinds of foundation treatment methods, the manual cavity expansion pile and the squeezing reinforced concrete bulb pile, adopted the main buildings of a thermal power plant on the collapsible loess site, this paper takes various factors such as the safety, economy and others into comprehensive consideration, and makes the demonstration and optimization design of the feasible foundation treatment methods for providing some experiences for the future foundation treatment in the collapsible loess areas.
