论大温差干旱地区混凝土桥梁裂缝预防措施

Preventive Measures of Concrete Bridge Crack in Drought Environment Area with Large Range of Temperature

在大温差干旱环境的影响下,大温差干旱地区尤其是新疆地区的混凝土桥梁容易产生裂缝,严重影响桥梁的安全使用。针对新疆大温差干旱地区特点,分析混凝土桥梁开裂问题,讨论在大温差干旱环境下,混凝土桥梁的设计方案和使用材料选择应考虑的因素,以提高混凝土桥梁的抗裂能力及桥梁工程的质量。

Under the impact of large range of temperature and drought envlronmem, cracks easily apl：,~a~ ,~ concrete bridge in Xinjiang, which seriously affect the safety of bridge. According to the characteristics of large range of temperature and drought of Xinjiang, the paper analyzes the problem of concrete bridge crack, discusses design plan and factors should be considered in materials selection of concrete bridge, in order to improve the ability of anti-cracking and quality of concrete bridge engineering.
