紧邻既有运营地铁的换乘车站微扰动拓建技术研究

在已建成地铁邻近区域建设新线路换乘车站的需求日益增加,而地铁和换乘车站的建设过程中,对于既有运营中线路的保护要求也越来越高。以上海轨道交通14号线云山路站工程为例,分析了换乘车站拓建过程中的重难点,通过围护跳打施工、电渗法隐患超前检测、挖土及障碍物拆除组织优化、钢支撑自动应力补偿、新老车站无缝连接等微扰动拓建技术,保障了既有地铁车站及线路的运行安全,可为类似工程提供借鉴。

城市既有建筑群地下空间拓建技术与工程应用

城市既有建筑群地下空间拓建是当前城市建筑行业发展的重点,通过对地下空间的拓建,能够节约更多土地资源,实现对建筑空间的合理利用,推动建筑行业朝着更好方向发展。针对拓建技术,工作人员要有正确认识,为整个拓建施工质量的提升打下良好基础。因此,本文首先阐述城市既有建筑群地下空间拓建方式,然后分析城市既有建筑群地下空间拓建技术,最后围绕明确施工流程、应用注意事项两点,对拓建技术在工程中的应用进行探讨。

The Risk Evaluation of Enterprise Technological Innovation Network Based on Extenics

Growing competition has prompted enterprises to choose construct Technological Innovation Network to promote innovation, however the innovation network is a risky innovation system, how to carry out a comprehensive risk assessment of the innovation network is particularly important. This paper focused on the technological innovation network risk analysis, used extenics to define which risk levels should these various risk factors in technological innovation network belongs to. And used Shanghai Caohejing hi tech park to do the empirical research, comfirmed risk factors which have the larger influence on technological innovation network.Enterprises can face them as the main objects of enterprise risk management, in order to improve the success rate of the innovation of the enterprise technological innovation network.
