Simulation test system for underground construction in city

Abstract

An urban underground engineering simulation test system includes a simulation box, a loading device, a loading oil circuit system, a groundwater simulation system and a data acquisition system. There is a horizontal loading plate in the simulation box, which can move horizontally to load the simulation material horizontally under the drive of the horizontal loading device, and the vertical loading device can load the simulation material vertically. There are several layers of horizontal water inlet pipes in the simulation box. According to the actual situation of groundwater in the underground project, the groundwater level and water pressure of different aquifers are simulated respectively, and the groundwater impact test is carried out. The empty size of the simulation box is 8 cubic meters, and a large-scale simulation test can be carried out. Therefore, this system has the remarkable advantages of realizing complete true three-dimensional hydraulic loading, large-scale simulation, water-soil coupling simulation, automatic loading and data acquisition, strong versatility, and multiple functions. It can realize various urban subway projects, tunnels and underground tunnels. Three-dimensional simulation test of chamber engineering, foundation and foundation engineering, special underground construction method, slope engineering, earth retaining structure, etc.

Description

technical field [0001] The invention relates to an urban underground engineering simulation test system, which is especially suitable for performing simulation tests on subway engineering, tunnel and underground cavern engineering, foundation engineering, special underground construction methods, side slope engineering, soil retaining structures and other underground engineering. [0002] The urban underground engineering simulation test system of the present invention is the result of the national 211 project construction project of the "National Key Discipline" of Geotechnical Engineering of China University of Mining and Technology (Beijing). Background technique [0003] At present, most domestic simulation test bench devices are specially designed and developed for specific projects, and can only simulate a certain type of underground engineering, that is to say, the current simulation test system is not universal. For example, Hunan University has studied the pile-soil...
