【摘要】：随着国民经济的快速增长,建筑行业呈现出迅速发展的态势,特别是最近十年,伴随着一些高层超高层建筑的出现以及地铁、地下商场、隧道等大规模地下空间的开发,出现了越来越多的深基坑工程。随着基坑的深度不断增加,面积越来越大,场地条件趋于复杂化,施工周期更长,工程成本控制愈加严格,为深基坑工程项目的实施带来了诸多问题。传统的基坑支护结构设计方法面临协同设计效率低下、数据传递可靠性差、信息表达不清楚等缺点,完全不能满足深基坑工程相关的质量、安全、经济、技术等方面的要求。实现BIM技术在深基坑施工阶段的应用成为大势所趋。本文分四个部分对BIM技术在深基坑施工中的应用进行了研究:1)对BIM技术在深基坑工程中的应用现状进行了详细分析,并对当前高层建筑深基坑施工过程中出现的问题及原因进行探究,指出采用BIM技术实现深基坑信息化施工的必要性和紧迫性。2)就多层内支撑深基坑施工过程中容易出现的问题,提出了进行深基坑围护结构施工、内支撑系统施工、土方开挖作业、支撑梁换撑及拆除等关键工序实施过程中的技术要求,并提供了常见问题的处理措施及方法。3)针对深基坑施工过程中BIM技术应用的方法进行了详细分析。本文在对BIM核心技术分析的基础上,提出了深基坑施工过程BIM应用的方法。鉴于目前国内深基坑信息化施工的要求,对BIM技术在深基坑施工过程信息化监测中的应用进行了探索。针对深基坑施工BIM应用的价值优势,本文从不同层面进行了详细分析。4)以近海地区某多层内支撑深基坑工程项目为例,采用BIM技术实现了深基坑施工模型的创建;并通过BIM软件的碰撞校核功能对深基坑支护结构施工方案的合理性进行了判断;采用BIM软件实现了工程量清单的自动统计;通过进行4D模拟的方法对深基坑施工关键节点施工进行了预演;利用BIM软件的出图功能及施工图纸管理功能,实现了深基坑施工过程中图纸文档的高效管理;采用BIM结构分析软件Robot对深基坑开挖不利工况进行分析,为关键工序的安全施工提供了技术保障。最后,对目前深基坑施工阶段BIM应用存在的技术问题进行了分析,并对未来的发展趋势进行了展望。
[Abstract]:With the rapid growth of the national economy, the construction industry has shown a rapid development trend, especially in the last decade, along with the appearance of some high-rise high-rise buildings, as well as subway, underground shopping malls. With the development of large scale underground space such as tunnels, more and more deep foundation pit projects appear. With the increasing depth of foundation pit, the area becomes larger and larger, the site conditions tend to become more complicated, and the construction period is longer. More and more strict engineering cost control for the implementation of deep foundation pit project has brought many problems. The traditional foundation pit support structure design method is faced with low efficiency of collaborative design and poor reliability of data transmission. The information expression is not clear and so on, which can not satisfy the quality, safety and economy of deep foundation pit engineering. The application of BIM technology in deep foundation pit construction has become the trend of the times. This paper studies the application of BIM technology in deep foundation pit construction in four parts. The application status of BIM technology in deep foundation pit engineering is analyzed in detail. At the same time, the problems and causes in the construction of deep foundation pit of high-rise building are discussed. The necessity and urgency of using BIM technology to realize the information construction of deep foundation pit are pointed out. The technical requirements of the key processes such as the construction of the internal support system, the excavation of earth, the replacement of braces and the demolition of the supporting beams, etc. The methods of BIM technology application in deep foundation pit construction are analyzed in detail. Based on the analysis of the core technology of BIM. The application method of BIM in the construction process of deep foundation pit is put forward. In view of the requirement of information construction of deep foundation pit in China at present. This paper probes into the application of BIM technology in the information monitoring of deep foundation pit construction process, aiming at the value advantage of BIM application in deep foundation pit construction. This paper makes a detailed analysis from different aspects. (4) taking a multi-story deep foundation pit project in offshore area as an example, the construction model of deep foundation pit is established by using BIM technology. The rationality of the construction scheme of deep foundation pit support structure is judged by the impact checking function of BIM software. The BIM software is used to realize the automatic statistics of the bill of quantities. Through the method of 4D simulation, the construction of key nodes in deep foundation pit construction is previewed. By using the drawing function of BIM software and the management function of construction drawings, the efficient management of drawing documents in the construction process of deep foundation pit is realized. BIM structural analysis software Robot is used to analyze the unfavorable conditions of deep foundation pit excavation, which provides a technical guarantee for the safe construction of key processes. The technical problems existing in the application of BIM in deep foundation pit construction are analyzed, and the development trend in the future is prospected.
