Abstract:A scheme of examiningmeasuring and strengthening of biochemistry pool introdu
ced after its unequal settlement and appearance of cracks of the structure and etc is introduced,and the quantity of external prestressed strengthening and the temperature stress of external prestressed bar are put forward.The strengthened settlement is observed for 6 months,and the result makes out this scheme is feasible and available.
Keywords:pressure casting; external prestress; temperature stress; settlement observation
