Abstract

The invention provides a three-dimensional underground pressure-bearing water flow-subway tunnel structure interaction simulating device which comprises a model case, a linear tunnel structure system, a water feeding and draining system, a pressure-bearing water head control system, a loading system and a measuring system. The linear tunnel structure system is arranged in a sandy soil layer in the model case, and the water feeding and draining system and the pressure-bearing water head control system carry out control and simulation on the water head of the sandy soil layer to form a water-containing pressure-bearing layer. In the experiment system, the measuring system detects data in real time. The model case is used as a bearing device and matched with other systems to simulate the influence of a linear subway tunnel structure on underground pressure-bearing water flow regime and the influence of underground pressure-bearing water flow changes on the subway tunnel structure, the anti-floating design effect of the subway tunnel structure can be verified, the influence of underground pressure-bearing water flow on the anti-floating design effect can be evaluated, and the safety influence of local leakage on the subway tunnel structure can be evaluated.

Description

technical field [0001] The invention relates to the fields of civil engineering, tunnel and underground space engineering, and environmental engineering, and in particular to a three-dimensional underground pressurized water flow-subway tunnel structure interaction simulation device. Background technique [0002] In my country's most economically developed coastal areas along the river, there are underground aquifers and multi-layered confined aquifers widely distributed underground. In recent years, with the rapid development of the rail transit system, the construction of long linear subway tunnel networks is unavoidable for the regional groundwater environment. On the contrary, the dynamic evolution of the groundwater environment induced by regional groundwater pumping and recharge also plays a key role in the development of the long-term behavior of the linear tunnel structure. How to evaluate the interaction law of underground confined water flow-subway tunnel structure ...
