基于Civil 3D的防波堤扩建工程过渡段设计方案优化

很多港口扩建中,其防波堤堤头波况较为恶劣,新老防波堤之间的过渡衔接较为复杂,设计难度大,相应的施工偏差大,施工质量更加难以保证。基于国外某工程,通过采用垫层倒滤的设计原理,优化出一种护面块石拆除量最小的设计施工方案。同时结合Civil 3D的三维建模和二维出图的功能,给出一种应对各种复杂界面过渡的三维设计方法。结果表明,通过运用BIM三维技术和倒滤设计原理,能够清晰准确地完成新老防波堤的设计,同时三维模型为施工提供了准确可行的参考。

Optimization design for transition section of breakwater extension project based on Civil 3D

For the extension project of many port projects,the wave condition of the breakwater head is relatively bad and the transition and connection between old and new breakwater are complex.The design is difficult and the construction quality is more difficult to guarantee.Based on a foreign project,we optimize a design scheme with the minimum amount of removal armor blocks according to the design principle of cushion inverted filter.Combining with Civil 3D software's function of the 3D model and 2D drawing,we propose a 3D design method to deal with the transition of various complex interfaces.The results show that the design of new and old breakwaters can be clearly and accurately completed by BIM 3D technology and an inverted filter design principle.Meanwhile,the 3D model provides an accurate and feasible reference for construction.
