摘要:

随着深埋长隧道需求数量的增加,高地温热害问题越来越突出,严重影响到施工人员的安全及工作效率,需要根据地温的分布特征来对隧道高温地段采取必要的降温措施。结合大瑞铁路高黎贡山隧道的地质、地温实测资料及通过“谷地地理信息系统”获取的地形数据,采用基于地质演化历史计算原岩温度的数学模型,编制相应的计算程序对高黎贡山大瑞铁路隧道进行原岩温度预测,并对隧址区的温度场沿洞线方向进行简单划分,为隧道采用有效的降温措施提供必要的地温场数据。通过计算分析可以得出: 1)沿隧道向瑞丽方向,隧道原岩温度有先增大后减小的趋势,最高点温度为31.73 ℃; 2)隧道开始大约2.5 km以内及18 km至隧道终点段,隧道岩温在28 ℃以下; 3)2.5~18 km段隧道岩温为28~31.73 ℃,其中高于28 ℃区域需要采取实时温度监控措施。

Abstract:

With the increase of deepburied long tunnels, the high ground temperature disease becomes more and more serious, which affects the safety and efficiency of construction workers. Therefore, it is necessary to take cooling measures for the high temperature section of the tunnel according to the distribution characteristics of ground temperature. Firstly, the geological conditions, ground temperature monitoring data and topographic data obtained by GoodyGIS of Gaoligongshan Tunnel on DaliRuili Railway are studied. And then the rock temperature of the tunnel is predicted by mathematical models and corresponding calculation programs based on geologic history. Finally, the temperature field of the tunnel area is simply divided along the direction of the tunnel line to provide necessary ground temperature field data for tunnel cooling. The calculation and analytical results show that the temperature of the rock increases and then decreases along the direction of the tunnel to Ruili, and the highest temperature reaches 31.73 ℃. The tunnel rock temperature is below 28 ℃ within the tunnel starting about 2.5 km and 18 km to the end of the tunnel. The rock temperature of the tunnel between 2.5 km and 18 km ranges from 28 ℃ to 31.73 ℃, and the realtime temperature monitoring measures should be carried out to the area where temperature is above 28 ℃.

Key words: Gaoligongshan Tunnel, deepburied tunnel, ground temperature field, rock temperature, prediction of tunnel rock temperature
