高海拔寒区隧道保温防冻系统设计要点分析
The design essentials of thermal insulating and antifreezing system for tunnels in the high-altitude cold regions
摘要
Abstract
This paper discussed the effect of thermal insulating and antifreezing layer, main characteristics of frost damage and the main problems in the design of antifreezing and thermal insulation layer of tunnels in high-altitude cold regions, and analyzed the relationship between anti water drainage and anti freezing system. The design principles of anti water drainage and anti freezing thermal insulation system are put forward. From the perspective of the tunnel insulation design elements, the type of antifreezing and thermal insulation system, the design of heat insulation system of hole body, insulation design of drainage pipe outlet and insulation materials, a systematic analysis on the main points in the design of anti freezing thermal insulation system of tunnels in high-altitude cold regions is carried out, and some measures are put forward to improve the design for the insulation and anti freezing system of tunnels.关键词
