日本大成建设公司开始正式实施作为城市开发新领域而瞩目的大深度地下空间和岸线地基防灾的基础研究。该研究计划的主要目标是探讨迄今数据尚不充分的大深度建设工程时的地下应力状况和岸线地基因地震产生的液化现象等,以提高今后大型地下工程的设计施工技术。为此,横滨市技术研究所将引进大型离心力荷载试验设备。 该设备的最大特点是利用离心力和重力场的变化,能在地面上模拟出任意深度的地基模型,并按比例把实际作用于构筑物
Japan’s Dacheng Construction Co., Ltd. has begun to formally implement basic research on the prevention of large-scale underground space and shoreline disaster prevention as a new area of urban development. The main objective of this research project is to explore the underground stress conditions and the liquefaction phenomena generated by genetic earthquakes on the shoreline in large-scale construction projects that have not yet had sufficient data, so as to improve the design and construction technology of large-scale underground projects in the future. To this end, the Yokohama City Technical Institute will introduce large-scale centrifugal load test equipment. The most important feature of this equipment is the use of centrifugal force and changes in the gravitational field to simulate a ground-based model of an arbitrary depth and apply it to the structure in proportion.
