Abstract
The application of pre-stressed high-strength concrete pile foundation has limitations,in recent years,UHV transmission line project has been constantly exploring and optimizing the differentiated application of pre-stressed high-strength concrete pile foundations.Although the application technology is relatively mature,there is still no in-depth research on the comparative analysis of comprehensive cost.This article takes a typical UHVDC transmission line project as an example to study the economic feasibility of adopting pre-stressed high-strength concrete pile foundation in practical engineering,which conducts research on pre-stressed high-strength concrete pile foundation by comparing them with the foundation scheme of cast-in-place piles,and combining with the charging and comprehensive cost of transmission lines.It is found that the cost of pre-stressed high-strength concrete pile foundation is about 23%to 33%higher than that of cast-in-place pile foundation,but other costs are lower than those of cast-in-place pile foundation.When the foundation force is small and the geological conditions are good,the comprehensive cost of pre-stressed high-strength concrete pile foundation has economic advantage.关键词
