Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the present invention is further described:

like Figures 1~4 As shown in the figure, a test system for soil seismic response under special complex site conditions includes five parts: layered shear model box, displacement test system, bath liquid circulation system, patrol monitoring system and response data acquisition system. The layered shear model box consists of a bottom plate (1), an interlayer frame (2), an interlayer rolling system (3), a limit linkage plate (4), a rolling bearing (5), a bearing column (6), and a transverse shear brace (7), beam (8), rubber lining (9). It is characterized in that the bottom plate (1) is anchored with the vibrating table (10) by bolts, the bottom interlayer frame (2) is connected to the bottom plate (1) by welding, and the other interlayer frames (2) are vertically equidistant and parallel. Arranged on the bottom plate (1) and connected by the interlayer rolling system (3), so t...

Abstract

The invention relates to an experimental test system for soil earthquake response under special and complex site conditions, which comprises five parts, namely a laminar shear model box, a displacement test system, a bath foam circulation system, a patrol monitoring system and a response data acquisition system, the device is characterized in that the adopted displacement measurement system is stably connected with the layered shear model box, the relative displacement of a soil body and an engineering structure in the vibration direction can be directly measured by adjusting the positions of the steel pipe combination fixing frame and the laser displacement meter, and the test efficiency is greatly improved. Circulation of water and cooling liquid is achieved by arranging the dripping bath circulating pipe and the copper cooling pipe in the layered shearing box, and the flow and temperature of the liquid bath circulating system are adjusted by combining real-time monitoring of the water content and temperature of the soil body through the inspection monitoring system, so that the water content and temperature of the soil body reach target threshold values; various special complex site environments such as site liquefaction, season alternation and freezing and thawing cycle can be effectively simulated.

Description

technical field [0001] The invention relates to an indoor model test system, in particular to a test system that can be used for soil seismic response under special complex site conditions. It can test the horizontal and vertical displacement of the soil during the shaking table test, and realize the automatic monitoring and acquisition of the displacement response of the soil or engineering structure foundation under the action of earthquake through the connection of the sensor, the data acquisition instrument and the computer, and carry out the free field. and experimental research on vibration mechanism of engineering structure foundation. Background technique [0002] Since the 1990s, the performance-based seismic design method has gradually replaced the traditional strength discrimination method as the dominant idea in the seismic design of underground structures, which requires engineering structures to meet various predetermined functional and performance target requi...
