Tunnel Design

At present, the tunnel design specifications in China do not provide a clear and systematic intelligent evaluation system of tunnel frost damage in cold regions. Based on the research results of 122 seasonal frozen soil tunnels in high-latitude areas of China, four key influencing factors of geohydrology, temperature, surrounding rock, and engineering measures were determined, the intelligent fuzzy comprehensive evaluation model was established, the weights of all factors were considered, and the intelligent evaluation technology system of tunnel frost damage in cold areas had been put forward. Meanwhile, the rationality of the intelligent model was verified by a specific engineering case. The research suggests that the intelligent evaluation model of tunnel frost damage proposed in this paper can accurately describe the relationship of influencing factors of tunnel frost damage in cold areas, the weight of each influencing factor is calculated by using analytic hierarchy process, and the main risk sources of tunnel frost damage in cold areas are found out. The intelligent evaluation model is an efficient and practical method for Intelligent prediction of frost damage. By using the subordinate function method, the improvement from qualitative analysis to quantitative index calculation is realized. The blindness of engineering analogy construction is avoided, and the scientificity and accuracy of renovation measures for frost damage have been improved. At the same time, the research results provide a theoretical basis for the improvement of the intelligent evaluation system of tunnel frost damage in cold regions.

Soil Cutting

The main causes and influencing factors of artificial side soil slope slide of soil-cutting in seasonal frozen area are analyzed and put forward, and a mechanical theoretical model form is also put forward. Based on checking computation of artificial side slope saturated soil stability in melting period, it provides effective measures by adopting drainage to stabilize side slope instead of cutting it to keep soil-cutting side slope stable in the seasonal frozen area. Then the comprehensive stability technology of side slope by introducing geotextile as lower levels drainage and by adopting net geotextile lattice to stabilize soil and planting Malian grass.
