Abstract

With the rapid development of ultra-high voltage power grid, plenty of transmission towers are built on soft soil area and the foundation of tower should be designed for economical and security reasons. The mechanism and application of the new micropiles foundation are discussed, which have many advantages in design and construction stage, such as accurate calculation, loading transfer clearly, convenient installation, easily installment within confined spaces and cost reduction. Traditional large-diameter pile foundation is a main way on soft soil layer in the past fifty years. By mechanism analysis, some disadvantages had been achieved and the kind of foundation is inadaptable in many engineering site. By a ultra-high voltage power grid project, the transmission tower foundation is designed using the two differential methods and the fouandtion plans had been drawn and quantities comparison analysis had been conducted. Some meaningful conclusions proposed which can provide a reference for similar project.
