Comparison analysis of micropile and slab foundation for transmission tower

摘要

Transmission tower is constructed quickly in China and the foundation of tower should be studied for economical and security reasons. A simplified analytical is presented for the mechanism of the new micropiles foundation, which have many advantages in design and construction stage, such as accurate calculation, loading transfer clearly, convenient installation and cost reduction. Slab foundation is a traditional type and building as a main way 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 real project, the design plan and construction quantities had been drawn and comparison analysis had been conducted. Some meaningful conclusions proposed which can provide a reference for similar project.
