高原地区由于地势较高,氧气浓度低、环境极为恶劣,加上环境温度通常较低,所以进行桥梁的施工工作难度较大,由于长期寒冷而形成的冻土层,硬度较大,不易挖掘,在这种恶劣的条件下开展施工工作,对施工工艺和技术是一个极大的考验。施工人员在这种条件下施工,要结合当地的实际环境条件和地质状况,合理选择施工方法,制定与之相匹配的施工工艺,以保证桥梁施工的顺利开展。 Due to the high altitude, low oxygen concentration, extremely harsh environment and generally low ambient temperature in the plateau, it is more difficult to carry out the bridge construction work. Due to long-term cold, the frozen soil layer is hard and difficult to excavate. Carrying out construction work under such harsh conditions is a great test of construction technology and technology. Construction workers under such conditions of construction, combined with the actual local environmental conditions and geological conditions, a reasonable choice of construction methods, to develop matching construction technology to ensure the smooth construction of the bridge.
