Referring to fig. 1, a planning and designing method for electric power construction projects in multiple areas includes the following steps:
s1, marking an area needing power construction as a construction area, and determining the types and the number of transformers according to the power consumption scale in the construction area so as to determine the transformer substation scale in the construction area; when a plurality of areas are built in the building area, transformer substations with corresponding specifications are required to be correspondingly built, and the scale of the transformer substations is required to be determined according to the area of the building area in the plurality of areas and the power load of users;
s2, calculating the construction area of the transformer substation through the scale of the transformer substation in the construction area; the areas of the substations with different specifications are different, and the construction area of the substation comprises the area of the main body of the substation and the safety area reserved around the substation and arranged outside the area of the main body of the substation, so that the construction area of the substation meets the construction requirement;
s3, performing preliminary site selection in a construction area based on the construction area of the transformer substation, and marking each transformer substation construction position conforming to the construction area of the transformer substation as each construction point to be selected; the step of preliminary site selection in the construction area is as follows: scanning satellite map information in a construction area according to the construction area of a transformer substation in the construction area, positioning positions conforming to the construction area of the transformer substation, excluding positions which are larger than the maximum length of a preset line, have average topography lower than the surrounding topography of the medium-voltage line and reach the preset height, have the distance to a main traffic road larger than the maximum length of the preset main road and have the distance to a pollutant factory smaller than the minimum distance of the preset pollutant factory, and marking the positions conforming to the construction requirement of the transformer substation in the construction area as to-be-selected construction points, wherein the distance to the medium-voltage line is larger than the maximum length of the preset line, so that the power transmission and the cost are increased; the average topography is lower than the surrounding topography to reach the preset height, so that the accumulated water of the transformer substation is serious, and the safe operation of power equipment in the transformer substation is further affected; the distance from the main traffic road to the maximum length of the preset main road can increase the construction cost and the later maintenance cost of the transformer substation; the fact that the distance from the pollutant generating factory is smaller than the preset minimum distance of the pollutant generating factory can enable the transformer substation to be affected by pollutants, and operation and maintenance cost of the transformer substation is further increased.
S4, monitoring and analyzing the geological conditions of the to-be-selected construction points to obtain geological coincidence parameters of the to-be-selected construction points, wherein the geological coincidence parameters comprise soil water content, acid-base corrosion of the soil, soil firmness and influence of peripheral slopes; the geological coincidence parameters of each point to be built are used for analyzing the difficulty of the construction of the transformer substation and the influence condition of the soil on the construction of the transformer substation and the later maintenance. The water content of the soil and the acid-base corrosion of the soil in the geological parameters can influence the electric power equipment buried in the soil; the firm intensity of the soil can influence the construction of the transformer substation; the influence degree of the peripheral side slope can reflect the influence condition of the side slope existing around the transformer substation on the transformer substation, and the serious influence of geological disasters generated by the peripheral side slope on the transformer substation is prevented.
The geological condition monitoring and analyzing steps of each construction point to be selected are as follows:
the first step, the water content and acid-base corrosiveness of the soil of each construction point to be selected are obtained by sampling and analyzing the soil of each construction point to be selected in the construction area,and respectively record it as

The weight coefficient of the water content and the acid-base corrosion degree of the soil, the weight coefficient of the solid strength of the soil and the weight coefficient of the influence degree of the peripheral side slope are respectively represented, and e represents a constant. The invention can fully reflect the influence of the soil of each construction point to the construction and later operation and maintenance of the transformer substation by collecting the water content, acid-base corrosion and solid strength of the soil, thereby preventing the electric equipment buried in the soil of the transformer substation from being damaged frequently due to the soil at each construction point to be selected, increasing the later operation and maintenance cost and improving the comprehensiveness and effect of site selection of the transformer substation.
The peripheral slope distribution condition of each construction point to be selected in the construction area comprises a slope orientation angle, a distance between the slope and the construction point to be selected, a slope gradient and a slope length, and the peripheral slope of the construction point to be selected can have hidden danger of landslide in severe weather, so that the safety of a transformer substation is seriously influenced.
In the concrete analysis, the direction angle of the side slope influences the direction of the side slope, the angle between the side slope and the transformer substation is 0 degree when the side slope is opposite to the transformer substation, the safety influence degree of the side slope on the transformer substation is maximum, the side slope landslide does not influence the transformer substation when the angle between the side slope and the transformer substation is 90 degrees to 270 degrees, the side slope landslide degree is also related to the distance between the side slope and the transformer substation, and the gradient and the angle of the side slope, and the influence degree of the side slope on the transformer substation can be obtained by analyzing various numerical values of the side slope.
The specific analysis mode of the influence of the peripheral side slope of each to-be-selected construction point in the construction area is as follows:
