摘要:利用BIM技术，建立了湖南广电节目生产基地项目深基坑支护桩锚三维信息模型，实现了预应力锚索的预建造，辅助工程师提前发现了图纸中存在的问题，并采取相应措施进行了处理。通过BIM技术的应用，重点发现并解决了原设计图纸中预应力锚索的碰撞问题，将碰撞报告提交设计院进行了图纸优化设计，并制作了三维可视化交底动画，为项目深基坑支护工程按期、保质完成提供了强有力的技术支持，取得了良好的经济效益与社会效益。

Abstract: The 3D information model of deep foundation pit support of the Hunan Broadcasting System Program Production Project is built through using BIM technology, which brings about the pre-construction of prestressed anchor cable, assisting the civil engineers to detect the construction problems earlier and to take relevant measures to avoid risks.The application of BIM technology is especially for identifying and resolving the collision problem of the prestressed anchor cable in the original design drawings, and then the collision report is submitted to the design institute for the optimization design of the drawings.Meanwhile, the 3D visualization disclosure animation is made for powerful technological support to the project completion punctually and highly-qualified.As a result, considerable economic benefits and significant social benefits are achieved.
