浅议港工建筑物的设计使用年限 - In order to keep the highway working normally , the thickness of the road has been improved and the extra large amount funds are invested
要在超重运输的条件下保证路面的设计使用年限，就必须增加路面的厚度，造成建设投资大幅度增长。 - In line with the theories of the present pavement designs , the cement concrete pavement , with normal performance in the structure of every layer , ideal interlayer contact as well as good designs and construction , will usually not break until a long time of use or the time designed
按照现行路面设计理论，路面结构各层性能正常、层间界面接触理想、设计和施工质量良好的水泥混凝土路面，一般要经过长期使用且达到其设计使用年限后才会开裂破坏。 - Available empirical results indicate that the creep of reinforcement strongly influences the overall behavior of rs structures , which is demonstrated by excessive deformations . different creep tests are discussed and the test methods to obtain the two kinds of creep curves are compared in this thesis . the methods of how to determine the reduction factor according to long - term strength of creep or allowable strain during the services life are presented
文中介绍和研究了不同的蠕变试验手段，比较了获得两种蠕变曲线的试验方法，并给出了两种蠕变曲线一定范围外推的数据处理方法;给出怎样根据设计使用年限的长期蠕变强度或容许应变来确定蠕变折减系数的方法，并用计算实例来说明。 - According to the theory that the probabilistic distribution of seismic intensity fits extreme value type hi , a method to confirm seismic power that is pertinent to the period of expectant use is discussed . at the same time , the way to deal with seismic details is given by introducing system coefficient and coefficient factor . in summary , this paper provides engineers a seismic design method that is pertinent to the period of the building ' s expectant use
根据地震烈度的概率分布符合极值型的理论，探讨了在相同概率保证下，不同设计使用年限与设计基准期之间地震作用的关系以及不同设计使用年限与设计基准期之间抗震构造的关系，引入了对应于设计使用年限的地震作用调整系数和抗震构造折减系数及其体系影响系数和局部影响系数，发现了现行抗震鉴定标准所采用的设计使用年限。
