Our country firstly put forward such design principle of Qinghai-Tibet railway engineering as "lower temperature actively, reduce the heat into the subsoil, and assure the heat stability of frozen earth for the quality stability of construction", creatively adopt such corresponding measures of frozen earth construction problem as: for the poor frozen earth developing section, line should avoid as possible;for the geology of ice at high temperature and unstable frozen earth zone, the method of bridge instead of subgrade shall be adopted;in subgradeconstruction, such facilities as heat stick, rubble ventilation subgrade , rubble ventilation berm, ventilation pipe subgrade and laying heat preservation board etc shall be adopted to raise the stability of frozen earth subgrade;during the excavation of bridge, culvert , foundation pit and scouring prevention trough, creatively adopt single-tooth knapper and solve the problem of frozen earth excavation;during the construction of bridge and culvert, durable concrete and three-step maintenance method are adopted to assure the outside and inside beauty of structure.

我国在世界上首次提出"主动降温、减少传入地基土的热量、保证多年冻土的热稳定性，从而保证修筑在上面的工程质量的稳定性"的青藏铁路工程设计原则，创造性地采取了解决冻土施工难题的相应对策：对于不良冻土现象发育地段、线路尽量绕避；对于高温极不稳定冻土区的高含冰量地质，采取"以桥代路"的办法；在路基施工中采用了热棒、片石通风路基、片石通风护道、通风管路基、铺设保温板等多项设施，提高冻土路基的稳定性；在桥涵基坑、挡水埝基槽开挖中，创造性地应用了单齿破碎器，解决了冻土开挖难题；在桥涵工程施工中，采用了耐久性混凝土，采用了三步养生法，保证了结构物内实外美。

Road brief: Germu (109-2864), 120KM, most was asent, flat in the first 30KM, 30-40km we lost cellphone signals. We driven along by Qinghai-Tibet Road (109) toward the south, via the lorn and stark Gobi Desert in north-west China, the Qulun Brige which was called "One step to the Heaven"(3400meters altitude), romantically Unfreezing Nachitai spring (altitude 3776m), Non-melt Kunlun Snow of June(Altitude more than 6KM), fierce Wind blowing entrance of Kunlun Montains(altitude 4767m), and the Yuzhu montains which was 10km east to the Kunlun entrance.

Germu--West Desert， 140KM 宿：西大滩 slept： West Desery 路况：格尔木-(109-2864)120公里，基本都是上坡路，前30公里较平坦，出格尔木30－40公里手机没信号，早上沿青藏公路（109 国道）南下，经过大西北苍凉悲壮的戈壁滩、"一步天险"的昆仑桥（海拔3400米）、传奇色彩的纳赤台不冻泉（海拔3776米）、常年不化的"昆仑六月雪"（海拔6000米以上）、狂风怒吼的昆仑山口（海拔4767米）、遥望昆仑山口以东10公里处的玉珠峰。
