| 1. | Advancing load stress 升高载荷应力 |
| 2. | Over - time working , over - loading stress plus un - healthy diet caused her serious problems of poor digestion , immune system , female menses 她算是科技新贵族的中高薪阶级,但是却为了高薪的工作牺牲了身体的健康,想想实在不值得。 |
| 3. | On the basis of a great deal of calculation , a simple and rational calculation method of the loading stress of utw pavement is brought forward 通过大量计算,提出了utw路面荷载应力实用计算方法。最后,介绍了我国第一条utw路面试验路的修筑情况。 |
| 4. | Fatigue property of lean concrete should be studied when the material is set as base course since it withstands the repeated actions of load stress and temperature stress 摘要贫混凝土用于路面基层时,由于受到荷载应力和温度应力的反复作用,需研究其疲劳特性。 |
| 5. | Material notch sensitivity test is a method which is used for certain material to measure and estimate the capability of resisting cr ack growth on the occasion of existing load stress and notch 材料缺口敏感性试验是测定或评价某一材料在静载荷的应力条件下和有缺口的情况下,抵抗裂缝扩展能力的一种方法。 |
| 6. | Based on the present research productions , load stress and temperature stress of asphalt pavement with lean concrete base are additionally calculated and the influence of correlated factors is analyzed 在现有研究成果基础上,补充计算了贫混凝土基层沥青路面的荷载应力和温度应力,并分析了各因素的影响。 |
| 7. | Since the louisville utw experiment , although , some utw experimental projects have been built in united state , the loading stress of utw pavement has not been analyzed by theoretical calculation 作为一种新型、有效、快速、经济且简便的旧沥青路面维修技术,虽自lousiville试验路后在美国已进行了大量试验路研究,但在路面结构荷载应力分析方面尚属空白。 |
| 8. | When the load stress and temperature stress of road slabs combine in a disadvantaged state , pavment structures may be distressed when a large axle load loading one time , the fatigue of pavment structures becomes insignificant 当路面板荷载应力与温度应力的组合处于不利状态时,过大轴载的一次作用就可能造成路面结构的破坏,路面结构的抗疲劳性则无从谈起。 |
| 9. | The existing methods of structure design of concrete pavement with lean concrete base are analyzed , proving that the equivalent stiffness method is proper for calculating load stress but not for thermal stress 对贫混凝土基层混凝土路面现有结构设计方法的应力计算进行了分析,发现等刚度法用于双层板路面的荷载应力计算是可行的,但用于温度应力计算会引起较大的误差。 |
| 10. | The formula of axle load conversion in the standard has some problems , so respectively according to the corresponding formulas of load stress and fatigue equations of concrete pavement and lcb , the different formulas of axle load conversion and fatigue stress coefficients are put forward 针对规范中轴载换算存在的问题,分别根据面层和基层的荷载应力公式和疲劳方程,提出轴载换算公式以及疲劳应力系数。 |
