【摘要】 根据全国110个气象观测站的气象资料,采用新的方法推算了全国2%频率水泥混凝土路面最大温度梯度值,改进了我国公路水泥混凝土路面规范中所提出的方法。并且绘制了全国2%频率水泥混凝土路面最大温度梯度等值线图。更多还原

【Abstract】 In this paper,the maximum temperature gradient of concrete pavements with frequency of 2% is derived based on the 110 observation stations of weather by a new method which improves the method of the specifications of cement concrete pavement design for highway. Moreover the isogram chart of countrywide maximum temperature gradient of concrete pavements with frequency of 2% is plotted.更多还原
