板荷的英文
itaka
itako
例句与用法
- 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。 - The paper is based on innumerable practical heavy - load road data , deliberate heavy - load standard in detail through theoretical arithmetic , and bring heavy - load standard about cement concrete pavement and asphalt concrete pavement separately ; in the meantime , through a large quantity of cement concrete pavement stress calculation , the paper puts forward relation expression between load on concrete board and stress level under board ; meanwhile , the paper puts forward traffic classification about cement concrete pavement and asphalt concrete pavement ; through bearing board testing on each structure sheaf the paper finds the material modulus gets modified ; through comparing position equivalent rebound modulus to theoretical equivalent rebound modulus , the paper points out limitation of nomograph in course of cement concrete pavement design , whereby , puts forward modifier formulas about theoretical equivalent modulus
本文以大量的重载道路资料为主，从实际出发，结合理论计算，对重载标准进行了详细的讨论，分别给出了水泥混凝土路面与沥青混凝土路面的重载标准了；同时，通过大量的水泥混凝土板底应力计算，推导出了混凝土面板荷载与板底应力水平的关系式；给出了水泥混凝土路面与沥青混凝土路面的交通分级；通过对试验路各结构层进行承载板测试，发现现有材料模量较以前有了明显的提高；对比现场实测的当量回弹模量与理论当量回弹模量，指出现有水泥路面设计中的诺谟图不能完全符合现有道路材料，从而提出了对理论模量的修正公式。
