摘　　要：合理的施工与养护技术有助于提高高寒地区桥梁混凝土结构耐久性,探讨了合理的施工方法和养护技术,并采用不同的养护方式对西藏地区特殊自然环境下混凝土的力学性能进行了现场试验研究,总结出一套适应于西藏高寒地区气候的混凝土养生技术,即采用暖棚养护与养护剂养护相结合的方式,试验研究结果表明:该方法能够使混凝土的耐久性能得到显著地提高,具有很好的应用推广价值。Proper construction and maintenance technology is beneficial for improving the durability of concrete bridge structure in the cold area, which is discussed in this paper, and different mechanical properties of concrete under the special natural environment in Tibet area are studied based on in-situ test, and then a set of concrete health technology suitable for cold climate regions of Tibet is concluded which is namely the greenhouse curing and curing agent maintenance combination. Tests results show that this method can make the durability of concrete increases significantly.
