[0062] The following is a test tunnel in East China to further illustrate the zero-carbon tunnel design method based on the full life cycle theory.

[0063] In this embodiment, the middle section of the test tunnel of 1 km is used as the basic calculation unit. The inner diameter of the tunnel is about 12 m, the lining thickness is about 1 m, the clearance is about 5 m, and the slope is 0.5%. It is a single-hole, two-lane highway tunnel.

[0064] In this embodiment, the initial tunnel construction data is calculated based on the above data combined with existing tunnel engineering documents, such as "JTG-T3821-2018 Highway Engineering Estimation Indicators" and the like; the lamps inside the tunnel are arranged symmetrically, with an interval of 20m and a power of 50W, and the lamps are operated all day throughout the year. The jet fans in the tunnel are arranged symmetrically, with an interval of 200m and a power of 50W, and operate for 12 hours a day. The renovation work during the operation and maintenance period mainly considers the renovation of the tunnel lining, and considers completing the replacement of the tunnel lining once within the 100-year operation period, so as to calculate the initial tunnel operation and maintenance data; the initial carbon offset measures data are calculated based on the site data around the tunnel.

[0065] Figure 3 It is a schematic diagram of carbon reduction measures outside the tunnel in an embodiment of the present invention.

In this embodiment, light-guiding facilities and tunnel entrance light-reduction facilities are configured as specific types of lamps in the zero-carbon tunnel optimization design plan.

[0067] According to the above initial tunnel construction data, tunnel operation and maintenance data and carbon offset measures data, the total carbon emissions during the tunnel construction phase were calculated using a zero-carbon tunnel design device based on the full life cycle theory. 4 tCO 2eq The carbon emissions during the tunnel operation phase are 28.33tCO 2eq / year, the carbon emissions in the tunnel maintenance phase in the first year were 90.72t CO 2eq The carbon offset in the tunnel site is 79.06tCO 2eq / year, that is, the total carbon emissions during the tunnel operation and maintenance phase are approximately 39.99tCO 2eq / Year.

[0068] Because 2.86×10 4 tCO 2eq +39.99tCO 2eq / year>0, so the control module 50 controls the parameter optimization module 40 to optimize the parameters of the tunnel construction data, tunnel operation and maintenance data, and carbon offset measures data. After multiple iterations, the sum of the total carbon emissions in the tunnel construction phase and the total carbon emissions in the tunnel operation and maintenance phase is less than or equal to zero.
