| 摘 要： | 柴达尔-木里铁路沿线高温沼泽化多年冻土广泛发育，约20km的冻土路基采用了热管降温措施．借鉴青藏铁路的成功经验，热管的纵向和横向间距均设计为3m，并针对铁路东南-西北的不利走向，在阳坡布设了双排热管．为验证热管措施在多年冻土湿地路段设计参数的合理性，2008年底在柴达尔-木里铁路中段布设了热管冷却半径观测试验场，该观测... |

| Abstract: | Warm and swampy permafrost is distributed widely along the Qaidar-Muli(Qai-Mu) Railway,where about 20 km embankments are equipped with heat pipes.According to the successful experience in the Qinghai-Tibet Railway,3 m interval between heat pipes is designed.Taking into account the adverse trend of the railway,double rows of heat pipes are arranged at the bottom of sunny slopes.In order to confirm the validity of design parameter of heat pipes in swampy permafrost regions,a testing field for searching the co... |
