大跨度隧道管廊共坑施工与数字化建造技术
$42.15
公司目前承建的南京横江大道建设工程SG-2标,建设场地为淤泥质土,具有含水量高、孔隙比大、强度低、压缩性高、渗透性低等特点,是基坑工程中典型的不利地质条件。在城市市区施工隧道和管廊共坑建造较为少见,基坑全长1.59 km,开挖宽度39~63 m,开挖深度16.18m,根据公开文献报道,在淤泥质软土地区施工如此距离和跨度规模的基坑尚属首次,缺乏基础理论,施工组织和现场管理难度大。基于上述背景,首先介绍在本工程中所采用的各种专业施工技术,包括施工组织、地基加固、支护结构施工、降水施工、基坑监测等内容;并且基于关键施工技术和难点科研攻关工作详细阐述本工程先进创新性成果研究情况。此外,将介绍BIM技术在工程前期策划阶段、过程紧跟施工进度针对重难点技术问题开展的系列应用,如BIM实施方案策划;驻地标准化建设;基坑开挖、换撑、顶管顶进等方案模拟与优化;可视化交底;VR教育等进行详细叙述,为提升整体运营效率、管理效率,在智慧工地建设展开详述,分别介绍BIM平台、视频监控、环境监测、劳务和物料管理等多方面在本工程的应用;后在品质工程创建模块系统介绍该种系统先进的项目管理理念。基于上述内容的阐述,能够详实的再现整个工程建造过程,对于类似工程具有重要借鉴意义。文章图文并茂,采用大量图表和数字资源,针对相关工艺和场景进行三维可视化建模,借助二维码讲解技术,辅助专业基础薄弱的读者进行理解和体验,能够扩大读者范围。
