Multifunctional foundation pit model test system device, and application method thereof

Abstract

The invention relates to a multifunctional foundation pit model test system device which comprises a model box system and a soil loading-unloading and loading system. The model box system comprises amain box, water boxes and an up-down iron ladder; the main box is formed by steel plates, organic glasses, angle irons and bolts; two sides of the main box are assembled by the steel plates and are ribbed; sealing strips are arranged on connecting parts; the transparent organic glasses are integrally embedded into the steel plates so as to be used as observation window; the soil loading-unloadingand loading system comprises a soil accumulated place, a soil loading-unloading channel, an excavator, a movable steel beam frame and a pressurizing device; the soil accumulated place is formed by steel plates, angle irons and bolts through connecting; and the soil loading-unloading channel is connected to one end of the soil accumulated place. The multifunctional foundation pit model test systemdevice provided by the invention has the beneficial effects of simplicity in operation, high automation degree, diverse structure functions, capability of carrying out an indoor model test for testingthe influence of foundation pit excavation on the environment, capability of detecting a stress strain of a water body and pore water pressure, and capability of carrying out dynamic loading and static loading.

Description

technical field [0001] The invention relates to the field of foundation pit model test equipment, in particular to a multifunctional foundation pit model test system equipment and a use method thereof. Background technique [0002] Model test is a method to conduct scale-down research on specific engineering geological problems according to a certain similarity principle. It has become the most important method in the engineering field to obtain relevant data and check design defects by performing corresponding tests on scaled-down or proportional models. one of the research tools. my country's economic strength is becoming stronger and stronger, which is inseparable from the rapid development of urban construction. High-type, heavy-duty and large-scale buildings (structures) are emerging in an endless stream, which also increases the difficulty of construction technology. Foundation pit engineering is to ensure The importance of the retaining structure, groundwater control,...

AI Technical Summary

Problems solved by technology

Most of the existing data use engineering examples to analyze and illustrate the impact of foundation pit excavation on the surrounding area under the geological conditions of a specific area. However, there is almost no corresponding indoor model test in this regard, so relevant research is of great significance
