This invention discloses a comprehensive parameter design method for the cross-section of long-span highway tunnels. Using tunnel flatness ratio and equivalent initial support strength as two variables, and with tunnel safety and economy as dual objectives, it employs numerical simulation and regression analysis to establish evaluation indicators and objective functions for flatness ratio and initial support. Based on survey results, the range of variables for flatness ratio and equivalent initial support strength is determined. Safety constraints are defined according to safety requirements. A non-dominated sorting genetic algorithm is used to perform optimization calculations within the specified variable range and constraints to obtain mutually suitable tunnel cross-section flatness ratio and equivalent initial support strength. Furthermore, the equivalent initial support strength is transformed into support form and parameters, ultimately forming the optimal initial support parameters for long-span tunnels. This method overcomes the shortcomings of traditional long-span highway tunnel design methods that only consider safety or economy as a single objective, and solves the problem of relying on manual experience to determine the optimal flatness ratio and initial support parameters.

This invention provides a method for calculating the geothermal resources of high-temperature tunnels. It involves conducting a survey of tunnel heat hazard resources to obtain basic data including tunnel heat hazard temperature, exposure mileage, length, and lithological characteristics. Based on these survey results, the tunnel is initially divided into multiple heat hazard zones, and temperature sets are obtained. The lithological characteristics of the surrounding rock in different heat hazard zones are investigated, and test sample sets are collected. The thermal properties of the surrounding rock samples in the test sample sets are tested to obtain test results. The length and heat extraction depth of each heat hazard section are determined. Combining temperature, surrounding rock physical parameters, and annual average air temperature, the geothermal resources of the high-temperature tunnel surrounding rock are estimated and accumulated to obtain the total geothermal resources. By comprehensively considering the tunnel heat hazard resources, the lithological characteristics of the surrounding rock in the heat hazard zones, and the temperature data collected during tunnel construction, the geothermal resources of the high-temperature surrounding rock in high-temperature tunnels can be accurately calculated.
