Abstract: In order to solve the problem of invalid evaporation of the reservoir water surface in inland arid plain, we applied the partition board made of polystyrene plate and fiber cement(hereinafter referred to as the partition board) to the water saving and evaporation prevention. It is a new type light-weighted non-toxic and harmless material with large strength and good performance of anti-permeability. Through flexural loading test and on-site test, we verified its feasibility for water saving and evaporation prevention by covering it on the reservoir water surface. Results suggest that it has good anti-flexural performance, and its final stable size is 1 500 mm×600 mm (length×width).

Key words: reservoir in plain area, partition board, evaporation prevention, water saving test, load-displacement curve
