The invention relates to a load distribution based method for calculating recently planned annual line loss of a medium-voltage distribution network. The method comprises the following steps of: (1) calculating a load distribution coefficient of a typical load distribution line; (2) calculating a load distribution coefficient of an actual line; (3) virtualizing a return line, wherein parameters related to line loss calculation are all average parameters, and the loss of the return line is used as the average loss of the medium-voltage line of the planning area; (4) calculating the loss of a trunk line of the virtual line; (5) calculating the loss of a branch line of the virtual line; and (6) calculating the loss of the medium-voltage line in the planning area. The method has reasonable design, solves the problem that the failure of acquisition of the load data of a recently planned annual distribution network causes difficulty in line loss calculation, realizes the quick estimation ofthe line loss of the whole planning area and has the characteristics of simple operation, easier obtaining of collected data and short calculation time.

The invention relates to a concrete beam end and curved surface shear wall construction joint disposal device. The concrete beam end and curved surface shear wall construction joint disposal device comprises a concrete beam and a concrete shear wall. A construction joint is formed in the junction of the end of concrete beam and the concrete shear wall. A section steel shear resisting key is pre-embedded in the construction joint and penetrates through the construction joint, one part of the section steel shear resisting key is located in the concrete shear wall, and the other part of the section steel shear resisting key is located in the concrete beam. The invention further relates to a concrete beam end and curved surface shear wall construction joint disposal method. According to the concrete beam end and curved surface shear wall construction joint disposal device and method, due to the fact that the section steel shear resisting key is embedded, the high shear resistance of the section steel shear resisting key and the feature that anchor bars are welded on the section steel shear resisting key are utilized to solve the problem of force transmission between beam-shear wall joints; and due to the fact that a dense-hole steel wire mesh serves as a formwork of pouring of the construction joint, the penetration of rebars of the concrete beam and the section steel shear resisting key is facilitated, the adhesion force of the construction joint is increased, the construction measure cost is saved, the construction period is shortened, and the concrete beam end and curved surface shear wall construction joint disposal device and method have certain engineering application value for spatial abnormally-shaped concrete beam construction.
