| 摘 要： | 根据重庆地区气候特点、农村公路的荷载特点及水泥锶渣路面结构参数,利用弹性层状体系理论对水泥锶渣面层的温度收缩应力、温度翘曲应力、荷载应力及其迭加效应进行了分析。分析结果表明:由于水泥锶渣面层的回弹模量较普通水泥混凝土低得多,在温度和荷载共同作用下路面内应力小于其强度,不会产生收缩开裂,因而无需设置伸缩缝;通过对多条水泥锶渣试验路长期性能观测,表明不切缝的水泥锶渣路面性能良好,可推广到西部农村公路建设中。

| Abstract: | According to the climatic characteristics of Chongqing,load characteristics of the highway and structural parameters of the cement strontium slag pavement,the temperature contracting stress,temperature-warping stress,load stress and iteration effect of the cement strontium slag pavement are analyzed by making use of the elastic layered system theory.The analysis result indicates that: it is not necessary to set the expansion joint because the resilient modulus of cement strontium slays concrete is much lowe... |
