摘　　要：城市空间日趋紧缺,由此引发了地下空间开发的飞速发展,然而各类地下工程的安全运营都无一例外地受地下水动态变化的强烈制约,因地下水影响而引发了一系列新的岩土工程问题,其中尤为突出的是地下结构物的抗浮评价问题。对此,现有的规范尚未给出较为明确的规定,人们对此的认识也相当不统一;理论及概念层面的探讨较多,系统的试验及测试研究较少。详细介绍了用于研究地下水浮力作用机理的模型试验整体构思、试验装置设计及实施过程。With the development of urban, city space becomes less and less, and underground space is used more and more. However, it is concerncd with dynamic change of underground water, which often brings about series of geotechnical engineering problems. And anti-floating evaluation of underground structure is one of the significant questions. Regarding this, clear rules haven＇ t been given by existing criterion, and people＇s attitude on it is also quite different. And the systematic experiment is less than theoretical research. This article introduces the whole idea, tester design and actualization process of the model experiment for uplift action mechanism of underground water.
