冬奥广场高线公园三维模型的建立及应用

Establishment and Application of Three Dimensional Model of High Line Park in Winter Olympics Square

工业管廊是高线公园的重要组成部分,随着时间的推移,存在着设备设施老化、钢结构生锈腐蚀等问题,工业管廊弯头膨胀圈较多,上下管道空隙较小,走向复杂,密集度较高,互相遮挡较为严重,局部的数据模拟无法满足设计精度需求。针对冬奥广场高线公园的建设改造的问题,利用三维激光扫描技术快速实现管廊及其附属设施、现状基础的精准定位,制作管廊支架模型,细化工业管廊的平、立、剖面图,满足高线公园附属建构筑物改造设计需要,为冬奥广场高线公园的建设改造工作提供可靠的数据保障。

Industrial pipe gallery is the main component of elevated park,with the passage of time,there are facilities aging,steel structure rust corrosion problems,and the utility tunnel elbow point expansion ring more,smaller fluctuation pipeline gap,complex,high intensity,keep out each other serious,local data simulation can not meet the demand of design precision.In view of the problems in the construction and transformation of the High Line Park in the Winter Olympics Square,this paper used three Dimensional laser scanning technology to quickly realize the precise positioning of the pipe gallery,its auxiliary facilities and current foundation,made the pipe gallery bracket model and details the horizontal,vertical and sectional views of the industrial pipe gallery,so as to meet the needs of the transformation and design of the auxiliary structures of the High Line Park.It provided reliable data guarantee for the construction and reconstruction of the High Line Park in the Winter Olympics Square.
