Anti-Frost Heave Measures for Tower Foundation in DC Interconnection Project form Qinghai to Tibet
Frost-heaving is the key factor that impacts the stability of foundation in the frozen-soil region. In this paper, the conventional anti-frost heaving measures are improved by six treatment measures, such as cone cylindrical foundation, the replacement of heaving material, lubricant smearing and the application of glass steel formwork. These measures have been proved reasonable and effective through engineering practices.
