南水北调中线沙河渡槽开挖土石比计算方法探讨OA北大核心
Calculation method of soil-stone ratio for Shahe Aqueduct of MRP of South-to-North Water Diversion Project
为能够直观、准确地计算出复杂地形、地质条件下土石方开挖工程量，基于CASS7.0断面法，利用AU-TOCAD三维多段线、面域计算土石方工程量，并且结合南水北调中线工程沙河渡槽鲁山坡落地槽工程数据，提出了一种新的计算方法。该方法首先根据野外采集的原始地形点数据绘制出原始断面图，而后在DTM的基础上生成开挖后的数字地形图，并在数字地形图上标注出各类地质界线及界线点，再将各类地质界线及界线点插入到原始地形断面图中，最终形成包含原始地面线，设计地形线及多…查看全部>>
According to CASS7. 0 cross-section method, the quantities for earth rock excavation under complicated geological conditions are calculated perceptually and accurately by using 3D polylines and surface domain of AutoCAD. Thus, a new calcu-lation method is proposed by the engineering data of the section in Shahe Aqueduct of MRP of South-to-North Water Diversion Project. Firstly, the original cross-sectional diagram is obtained from the field terrain data, and…查看全部>>
