摘　　要：滨洲铁路地处我国高寒地区,冻土层深达2米以上,每年春融后土质疏松,导致接触网支柱及软横跨基础出现倾斜,严重危及行车安全。本文通过对冻害整治施工进行介绍,采用直埋杆基坑开挖、采用整杆器将支柱固定和软横跨基础加固方法,解决了接触网支柱及软横跨基础出现倾斜问题及基础护坡出现开裂的现象,确保了行车安全。滨洲铁路电气化改造有效提高列车运行速度,增加运输能力,降低运输成本,减少燃油带来的环境污染和能源浪费。对满洲里口岸和黑龙江西部地区与全国中心城市经贸交流具有重要意义。Harbin Manzhouli railway is located in the high cold area of our country. The permafrost layer is more than 2 meters deep. The soil is loose after the spring thaw every year, which leads to the inclination of the catenary pillar and the soft crossing foundation, which seriously endangers the traffic safety. In this paper, through the treatment of pillar frost damage, the construction of the treatment of frost damage is introduced. The method of fixing the pillar and strengthening the soft Cross Foundation by using the whole pole device is adopted in the excavation of the foundation pit with directly buried pole, which solves the problem of inclination of the pillar and the soft cross foundation of the catenary and the cracking of the foundation slope protection, thus ensuring the driving safety. The electrification transformation of Binzhou railway effectively improves the train operation speed, increases the transportation capacity, reduces the transportation cost, and reduces the environmental pollution and energy waste caused by fuel oil. It is of great significance to the economic and trade exchanges between Manzhouli Port and the central cities in the western region of Heilongjiang Province.
