设计使用寿命

Example Sentences:

	1.	However , the service life of existing bridges has not been up to the design service life 桥梁结构的耐久性是影响桥梁安全与使用的重要因素。
	2.	Considering the past research results , frost resistance of concrete using portland cement , and the designed service life of 100 years of testing bridge , the control indexes of high durability concrete are defined in this paper . mixture proportion of concrete used in pier column , coping , precast box beam and plate of bridge is designed based on the compact pile theory , and construction technique is studied also 结合课题组以往的研究成果,根据试验桥设计使用寿命100年的要求,确定出高耐久性混凝土的设计控制指标,基于最紧密堆积原理和最佳浆骨比原理对桥梁的墩柱、盖梁、预制箱梁和桥面板用高耐久性混凝土的配合比进行设计,并对其施工应用技术进行了研究。
	3.	Due to the influence of the corrosive agents in the outer environment , the resistance and dynamic reliability of the chemical structures declined with time very fast . and it is difficult for the chemical structures that with the normal design reliability level to fulfil their structural functions . on the condition that the design service life is confirmed , the design reliability level of the chemical structures should include the corrosive environment and its effect on the structures . based on agents ' corrosiveness fuzzy classification , this paper suggests a practical method on design reliability level decision - making of the industrial structures , which is very useful for the anti - corrosion design of the industrial structures 化工结构由于受到外部腐蚀性介质环境的影响，其承载能力及动态可靠度水平随使用时间衰减过快，按照普通结构设计可靠度水平设计的工业建筑常难以顺利完成设计使用功能.因此，在设计基准期预先确定条件下，化工结构的设计可靠度水平应综合考虑腐蚀性环境及其对建筑结构的影响特点来决策.根据介质腐蚀性模糊分级，提出了工业建筑设计可靠度水平的一种实用决策方法
