摘要
坝肩槽边坡保护层的开挖质量和进度控制对实现水利工程的安全高效施工具有重要的意义。针对坝肩槽边坡保护层爆破开挖,考虑保护层多轮廓、多倾角、高开挖质量要求等特点,提出了一种炮孔三维自适应布置算法,建立了基于该算法的三维几何计算模型,利用C#WinForm实现了人机交互操作界面设计,开发了炮孔三维自动布置系统。系统通过协调保护层顶部、底部、侧面开挖轮廓面内炮孔的二维布置,采用偏移轮廓线的方法确定各轮廓面内的炮孔排间关系,实现了炮孔的三维自动布置,有效地解决了复杂轮廓情况下坝肩槽边坡保护层爆破开挖轮廓孔的自适应布置问题,以及开挖边坡坡度较缓情况下炮孔底端未落在底部开挖面时的主爆孔布置问题。工程实例的设计结果表明:应用该系统能够自动、快速、高效地完成坝肩槽边坡保护层的炮孔布置。
The excavation quality and progress control of slope protection layer of dam shoulder groove is of great significance to realize the safe and efficient construction of hydraulic engineering.In view of blasting excavation of the slope protective layer,a three-dimensional adaptive layout algorithm of the blasting holes is proposed and a three-dimensional geometric calculation model based on the algorithm is established,which consider the characteristics of the protective layer,such as multi-profile,multi-inclination and high excavation quality requirements.Using C#WinForm to achieve human-computer interaction interface design,a three-dimensional automatic layout system of the blasting hole is developed.By coordinating the two-dimensional layout of the blast holes in the top,bottom and side excavation contour surface of the protective layer,and using the offset contour method to determine the row relationship of the blasting holes in each contour surface,the three-dimensional automatic layout of the blast holes is realized,which effectively solves the adaptive layout problem of the contour holes in the blasting excavation of the protective layer of the dam abutment groove slope under the complex contour,and the main blast hole layout problem when the bottom end of the blasting hole does not fall on the bottom excavation face under the condition of the excavation slope.The design results of engineering examples show that the application of the system can automatically,quickly and efficiently complete the layout of blasting holes of the protective layer of the abutment groove slope.
