桥头锥形溜坡的坡度(1:m_1),在路基高6公尺以内的,一般是m_1=1.25和m_1=1,而路基边坡的坡度(1:m),在一般情况下,m都是等于1.5的。衔接这两个不同坡度的曲线部分,在过去施工中,往往只凭眼力估计,找出几个点来,其结果常常是不够圆滑平顺。如一一进行计算,也是比较麻烦的。根据施工中的体会,
The gradient of the conical sloping slope at the bridgehead (1: m_1) is generally m_1 = 1.25 and m_1 = 1 within 6 meters of the subgrade. The slope of the subgrade slope (1: m) Are equal to 1.5. The curve connecting these two different slopes, in the past construction, often only by eye estimation, to find out a few points, the result is often not smooth and smooth enough. As one by one calculation, but also more troublesome. According to the construction experience,
