摘要日本TC全国委员会28日发表了一份关于日本当前地下建筑活动的委员会报告，其中包括支撑开挖和隧道掘进技术。这份报告是根据过去十年的技术文件和现有的施工记录编写的。在基坑支护方面，选择了近距离施工、支护墙开挖机械、深竖井开挖、地下水流保护措施等几个方面进行了介绍，并沿着了一些实例。在隧道领域，日本隧道的统计数据是根据公布的数据和问卷调查收集的。介绍了目前盾构法和城市新奥法施工的几个实例。最后，总结了1995年兵库县南部地震对地下建筑物的破坏情况，介绍了盾构法隧道施工的抗震设计新技术。
ABSTRACT The Japanese National Committee for TC28 has produced a committee report on current underground construction activities in Japan, including the technologies of braced excavation and tunneling. This report is based on technical papers and available construction records from the past decade. In the field of braced excavation, the topics of proximity construction, excavation machines for braced walls, deep shaft excavation, and groundwater flow preservation measures have been selected and introduced, along with some case records. In the field of tunneling, statistical data on tunneling in Japan has been assembled from published data and questionnaires. Several case records using current shield tunneling and urban NATM methods are described. Finally, damages to underground structures due to the 1995 Hyogoken-Nanbu (Kobe) Earthquake are summarized, and new earthquake resistant designs for shield tunneling and other technologies are introduced.
