Study on the Law of Influence of Seepage Field Anomalies on Displacement Field Induced by Leakage of Enclosure Structure

The leakage of an enclosure structure will cause abnormal changes in the seepage flow field, which turn can lead to deformation and affect surrounding geotechnical body. In this paper, a fiber-optic temperature measurement system is used detect location points station Qingdao subway during open pit excavation, variation field caused by obtained numerical calculation measurement. Then, simulation performed analyze effects anomalies on surface settlement. It found that point has significant influence settlement structure. With increase excavation depth, increases maximum position shifts downward. decreases when exists. volume also gradually with outward significantly. range becomes larger
