在后来的施工中，我们找到了一种既简单又能保证护栏板线形的方法。
首先用水准仪对每一个立柱位置的十字线进行水准测量。
firstly, the cross line of each column position is leveled with a level gauge.
（不需水准点，只测相对标高），根据这些数据计算出坡度。
according to these data, the slope can be calculated.
这样既保证了立柱顶面高度的平顺，又能使立柱顶距路缘石顶高度误差很小。
this not only ensures the smoothness of the top height of the column, but also makes the height error between the top of the column&the top of the curb stone very small.
