摘要
Abstract
In order to reduce the risks of transmission line construction,the drilled shaft foundation is adopted to replace the traditional manual shaft foundation.Through a comparison with manual shaft foundation,the feasibility of drilled shaft foundation is analyzed in terms of equipment mobilization plan,foundation design scheme,and environmental conservation measures.Based on an ultra-high voltage transmission line construction,a technical-economic analysis is conducted to determine the cost-effective construction length for mechanized road.The design of drilled shaft foundation is similar to that of manual shaft foundation.However,environmental protection measures need to be taken to reduce the impact of mechanized road.Moreover,the cost of drilled shaft foundation increases with the length of mechanized road.And the cost of drilled shaft foundation and manual shaft foundation is equivalent when the length of the road reaches 473 m.Drilled shaft foundation can be applied to transmission line construction with suitable terrain conditions.关键词
