QTR Company has mobilized adequate labor forces to unload the needed materials within the shortest timeframe .

组织足够力量，做到在最短时间内完成救灾物资到达后的卸车；

According to the test results , the temperature difference between steel and concrete can be taken as 15 ℃ in the design of composite bridges of QTR .

根据测试结果，青藏铁路结合梁设计中钢与混凝土温差可按15℃取值。

MOR , QTR Company and other railway administrations have quickly organized first-aid transport of quake-relief materials and personnel .

铁道部和青藏铁路公司以及各铁路局迅速组织开展抗震救灾人员和物资抢运。

Therefore , as the saying goes that The key to success or failure of QTR is subgrade , and the key to subgrade is permafrost .

因此有青藏铁路成败的关键在路基，路基成败的关键在冻土之说。

Therefore , studying on subgrade state in permafrost during QTR ' operation is a premise of assurance of its long-term , safe and reliable operation in permafrost region .

因此，开展运营期多年冻土区路基工程状态的研究，是保证青藏铁路多年冻土区路基工程长期、安全、可靠运营的前提。

With the simulation of the procedures of temperature descending and ascending in day and night on QTR , the temperature difference between steel and concrete were tested with FZS Temperature Auto Testing System .

采用FZS型温度数据自动测试系统，模拟青藏线昼夜降温、升温过程，对钢与混凝土的温差做了测试。

QTR Company has emptied the freight yards of Xining Railway Station and Xining West Railway Station so as to expand the unloading capacity to the maximum extent for the arrived quake-relief trains .

青藏铁路公司已把西宁站和西宁西站的货场全部腾空，最大限度的扩大卸车能力，用于救灾物资到达后的卸车和转运；
