| 8. | The intersection design is very important . but in the vertical design , the designer could n ' t use the form of contour lines to express accurately his design intension . he could only write few elevations of the pavement board corners because of the complexity in design progress and the bother in calculation
平交口立面设计，由于其设计过程复杂和计算麻烦，设计者很难以等高线等形式来准确地表达设计意图，只能是稀疏地手工计算标注若干高程控制点，设计成果对施工的指导及约束作用远不能满足要求。 |
