拟建成海至乳山公路,是将现有的二级汽车专用公路(简称专用线)作半幅再新建半 幅的方案,新建公路从威海至小庄为双向四车道,小庄至乳山是单向二车道,而且新建 半幅与老路的关系是忽左忽右,有合有分,时高时低,其环境噪声预测相当复杂,计 算工作量之大可想而知。而采用VBA软件编程,可使其计算简化,工作量大大减少。 The planned sea to Rushan highway is a plan to make the existing secondary motorized highway (referred to as the special line) halfway and then build a new one. The newly built highway from Weihai to Xiaozhuang is a two-way four-lane road and Xiaozhuang to Rushan is a one-way two Lanes, and the relationship between the new half-width and the old road is suddenly left and right, a combination of points, high and low, the environmental noise prediction is quite complex, the workload can be imagined. The use of VBA software programming, can simplify the calculation, greatly reducing the workload.
