弯拉强度 meaning in English
flexural-tensile strength
Examples
- At present , there are measures to reduce the shrinkage of the lime - fly - ash bound macadam and to increase the split strength . however , seldom of them are effective
减小二灰碎石的收缩及提高其抗弯拉强度的方法很多，但从目前的情况来看，非常有效的方法并不多。 - 3 . numerical simulations of the flexural process of the trisection specimens of concrete were executed , as well as the influence of configuration of aggregates on computing results was analyzed , by which showed that the method proposed is valid and feasible
3 .通过全级配混凝土试件三分点弯拉损伤破坏过程的数值试验,验证了所编程序的正确性。同时,讨论了骨料形态对混凝土动弯拉强度的影响。 - And two types of fatigue equations are put forward . according to them the fatigue stress coefficient of lcb for the concrete pavement structure and the structure coefficient of tension strength of lcb for the asphalt pavement structure are developed
并提出了贫混凝土两种形式的疲劳方程，据此推导了混凝土路面结构贫混凝土基层的疲劳应力系数和沥青路面结构贫混凝土基层的抗弯拉强度结构系数。 - Lastly , with the fatigue equation , the paper establishes the fatigue stress coefficient which is used in the load stress calculation for lean concrete as undersurface of cement concrete pavement , and the structure coefficient of flexural tensile strength which is used in the flexural stress check for lean concrete as base of asphalt pavement
利用得出的疲劳方程，建立贫混凝土作为水泥混凝土路面下面层荷载应力计算的疲劳应力系数，以及作为沥青路面基层时，进行层底弯拉应力验算的弯拉强度结构系数。 - With the developing highway communications , the traffic is increasing and axle is becoming heavier and heavier , all of these demand the high quality of cement concrete pavement the experience of past ten years in highway construction shows that the practical life time of cement concrete pavement is far more shorter than anticipated . damages such as cracking are offen occurred in first serval years they caused direct and indirect economic losses and bad social influences . in addition to control overloaded vehicles by means of administration , the compressive strength , bending strength wear - ability should be improved to solve all these problems
十几年的高等级公路建设实践表明，水泥路面的使用寿命远远小于其设计寿命，往往在通车几年后就出现一些病害，如坑槽、断板等病害，带来的直接、间接经济损失和不良的社会影响。解决这些问题，除了运用行政强制手段控制超载车辆外，必须提高水泥混凝土的弯拉强度、疲劳强度、耐磨强度、阻裂限缩能力，从而提高水泥混凝土路面的使用寿命。
