The pumped storage power station is mainly used for peak clipping and valley filling, and the working principle is that water in a lower reservoir is pumped into an upper reservoir when the power grid load is low, and the water in the upper reservoir is discharged for power generation when the power grid load is high. When the water head of the upper reservoir is larger and the capacity is higher and is limited by the regulation of terrains and geology, such as canyons, mountain and rock unstable areas, severe cold, intense heat or areas with frequent weather changes, an underground factory building structure is often adopted to avoid adverse effects of climate. The underground plant is an area for placing a water pump, a water turbine and a generator/motor, and is divided into a head type, a tail type and a middle type according to the arrangement position of the underground plant in a diversion power generation system, most of equipment in the underground plant is located underground, and the underground plant generally comprises a main plant, an auxiliary plant, a main transformer room, an installation room, a transportation hole, a valve room, a tail water hole or a ventilation hole and other structural areas.
Due to the complexity of tunneling construction and rock-soil medium, formation deformation, movement or settlement may be caused during the construction process and the operation process of equipment of the underground plant, which threatens personnel and equipment in the underground plant. Therefore, it is necessary to monitor the geological conditions of the pumped storage power station underground factory building during construction and operation. At present, many conventional means are to perform discrete sampling of stratum completely by means of vertical geological drilling or vertical shaft, or to establish the ground shape of a contour layer by combining remote sensing data, but the underground factory building excavated underground and the deep adjacent geological structure of the underground factory building are not fully and comprehensively obtained, so that great uncertainty exists in construction and subsequent maintenance, and adverse effects are caused on construction period and construction safety.
The Chinese patent application with the application number of CN202011596360.4 and the application date of 2020, 12 and 29 discloses a three-dimensional geologic model modeling method, which solves the problem of three-dimensional fine modeling of geology in petroleum exploration. The invention comprises the following steps: s1, collecting geological data, performing parameter interpretation on the geological data in geological three-dimensional modeling software, and establishing a geological model database; s2, building a geological structure model, a phase model and an attribute model, and building a matrix reservoir model; s3, according to geological data collected in the step S1, performing crack characteristic parameter interpretation and performing crack first constraint on the basis of a matrix reservoir model; s4, establishing a matrix reservoir model subjected to first constraint of the fracture in finite element analysis software, performing stress analysis experiments according to geological data in the step S1, simulating the generation of derivative fracture, and recording structural parameters of the derivative fracture; s5, parameter interpretation of derivative fracture structure parameters is made in geological three-dimensional modeling software, and secondary constraint of fracture is carried out on the matrix reservoir model, so that a three-dimensional geological model is obtained. However, the above-mentioned existing scheme does not solve the problem that the underground factory building and the deep adjacent geological structure thereof cannot be fully and comprehensively obtained.
The disclosure of this background section is only intended to increase the understanding of the general background of the present patent application and should not be taken as an admission or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.

F. If a hollow area exists between adjacent space closed stratum areas, the hollow area is confirmed to be a karst cave area or a groundwater area by inquiring relative dielectric constants, and the hollow area is filled without dividing grids. And for a hollow stratum area or an area with underground water, grid division is not performed, so that the workload of reconstructing a three-dimensional model can be simplified, and the time cost is reduced.
After the visual three-dimensional geological model of the underground factory building is built, whether sedimentation occurs in the diversion tunnel 1, the main factory building tunnel 2 or the tail water tunnel 3 at each sampling section 100 is confirmed, or the change of the elevation difference between the sampling section 100 and the ground surface contour line is observed, if the sedimentation or the change of the elevation difference exceeds a set sedimentation threshold value, an alarm signal is sent out. The sedimentation threshold may be set herein as a 10% x critical depth threshold;
the degree of sedimentation can be calculated as follows:s is the sedimentation height of the earth surface relative to the central axis of the diversion tunnel, the main plant tunnel or the tail water tunnel, < ->Is the maximum value of area loss of the sampling section 100 caused by surface subsidence; />Representing the distance of the horizontal boundary of the sedimentation zone relative to the longitudinal central axis of the sampling section 100; / >、/>And->The parameters S represent the range of the subsidence area or the severity of the subsidence depth, and if the values are too large, adverse effects on the underground factory building possibly exist, and the underground factory building needs to be reinforced by timely manual intervention or is filled with hollow or water-rich and incompressible stratum, or supports are additionally arranged in each tunnel.
