Research on DC UHV Transmission Line Foundation in Highly Corrosive Areas Based on Economy
The highly corrosive soil in gansu province region has strong typicality,especially in the context of the vigorous promotion and application of mechanized construction and the gradual improvement of environmental and water conserva-tion requirements.Therefore,the research on foundation selection is of great significance.This article compares the design and construction characteristics of applicable foundations based on anti-corrosion measures,construction processes,and foundation types.At the same time,typical foundation schemes for typical geological and DC ultra-high voltage transmis-sion line towers are compared in design,and further economic analysis and research are conducted based on corresponding quotas.It is recommended that anti-corrosion bag pile foundations should be prioritized in geological conditions with water,which can improve the efficiency of mechanized construction,shorten construction time,ensure anti-corrosion per-formance,and reduce construction risks.The research results have broken through the inherent idea of prioritizing the use of slab foundations in the design of ultra-high voltage transmission lines under strong corrosion conditions,and have guid-ing significance for the selection of foundations for direct current ultra-high voltage transmission lines in strong corrosion areas.
