In the summer of southern cities of China, the duration of high temperature becomes longer which requires stricter temperature control and crack prevention measures for mass concrete in construction. By using finite element method for unsteady temperature field and stress field a simulation is made for a pump station built in summer. The cement hydration velocity of this engineering is so high that makes the temperature control very difficulty. Through result analysis of different cases, some optimized measures which include surface preservation and water cooling are proposed. It has an important significance for concrete structure in the same area.
