摘要
根据左岸预应力排水渡槽的特点,参考我国公路桥涵设计规范,建立温度变化模式条件,对预应力排水进行渡槽温度效应分析,结合具体的工程实例进行了分析计算,得出在进行预应力排水渡槽设计时,温度效应作为对渡槽内力影响的主要因素之一,必须给予足够的重视而不能忽略不计.
Based on the characteristic of the left bank prestress drain aqueduct model, and referred to our national vehicular bridge culvert design specifications, the temperature fluctuation mode condition is built and prestress drain aqueduct temperature effect is analyzed, which incorporates specific engineering example proceeding analytical calculation and it is gotten out that when designing drain aqueduct, temperature effect which is one of the main ingredients to aqueduct internal force influencing, must afford adequate regard instead of ignoring.
