Shield construction method for passing through building under entrance and exit line of subway parking lot

The invention relates to the technical field of soil layer tunneling construction, in particular to a subway parking lot entrance and exit line underneath pass building shield construction method which comprises the steps that a building section corresponding to a subway line is determined, and a monitoring point is arranged in the building section corresponding to the subway line; a subway line close to a building section is selected as a test section, tunneling is carried out, monitoring data are obtained, and tunneling parameters are prepared based on the monitoring data; the method comprises the following steps: constructing a subway line passing through a building section according to prepared tunneling parameters, controlling the pressure of a soil bin to balance the soil pressure in the bin, selecting a subway line close to the building section as a test section before construction, tunneling and acquiring monitoring data, and preparing tunneling parameters based on the monitoring data, thereby reducin
