Abstract: In petrochemical construction, reinforced concrete pool is inseparable from production and construction. With the development of economy, people have increasingly high requirements for safety and environmental protection. In seasonal frost regions, the open underground pools tend to be affected by frost heaving and more attention should be paid to this. Taking a large rainwater monitoring pool in a domestic petrochemical plant as an example, this paper analyzes the frost heaving force of the open underground pool in frozen soil regions. Based on the calculation rules of pier foundation and retaining wall in accordance with existing code, a calculation method suitable for the pool is presented.

Key words: seasonal frozen soil, open pool, frostheave force
