基于BIM+3D激光扫描技术的复杂深基坑监测技术研究及应用
|
摘要
近年来,随着社会经济的飞速发展,城市综合体、超高层等大型工程越来越多,涉及到的地下室基坑具有大深度、大体量,不确定性因素多、风险高等特点。鉴于目前行业内存在的基坑安全传统监测信息采集手段落后、隐患问题发现滞后等问题,本文综合BIM、三维激光扫描等技术优势,对BIM技术、3D激光扫描在复杂深基坑监测中的拓展应用进行研究分析,以建设云平台为基础进行二次开发,实现深基坑监测数据的高效采集、储存、录入、分析及显示可视化的基坑安全监管平台,使参建各方都能在同一个信息平台中协同工作,大大提高基坑安全监管的时效性与及时性,对深基坑全过程安全管理具有积极的推动意义。
In recent years, with the rapid development of social economy, there are more and more large projects such as urban complex and super high rise, which involve basement foundation pits with great depth and volume, many uncertain factors and high risks. Given the industry foundation pit safety existing in the traditional monitoring information acquisition means lag behind, hidden problems found problem such as lag, this paper integrated BIM, 3 d laser scanning technology advantage, for BIM technology, 3 d laser scanning in complex deep foundation pit monitoring as the development of application for this paper, based on the construction of a cloud platform for secondary development, and implementation of deep foundation pit monitoring data acquisition, storage, input, analysis and display of visual platform for the foundation pit safety regulation, make cooperated-builing parties can work together in the same information platform, greatly improving the efficiency of the foundation pit safety regulation and timeliness, It has positive promoting significance to the whole process safety management of deep foundation pit.
