Abstract

The invention discloses a pipeline development prediction and early warning method based on dynamic tomographic scanning, comprising the following steps: interpreting the progressive erosion mechanism of aquifers and the dynamic response law of seepage field; establishing a fluid-solid coupling model of progressive erosion of aquifers; arranging monitoring wells to collect data Monitoring data; establishing a multi-source monitoring data interpretation model for progressive erosion of aquifers; calculating the current seepage field; calculating the erosion situation with the piping fluid-solid coupling model; updating the seepage field and iteratively calculated to the step size requirement. The method of the invention combines the characteristics of the piping fluid-solid coupling model and the advantages of the hydraulic tomography scanning to characterize the heterogeneous aquifer, and predicts the dynamic development of the piping channel. Real-time feedback and precise positioning have been greatly improved.

Description

technical field

[0001] The invention relates to the field of stratum lithology and geological structure geophysical exploration, in particular to a piping development prediction and early warning method based on dynamic tomographic scanning. Background technique

[0002] Seepage damage generally refers to the process of particle loss and further damage caused by seepage inside or at the bottom of the dam. 46.1% of dyke failures in the world are caused by seepage failure. According to the latest classification, seepage damage can be divided into four types: concentrated leakage erosion, contact erosion, subsurface erosion, and reverse erosion piping. Reverse erosion piping is the main reason for the failure of embankment instability. Historically, major embankments in my country, including the Jingjiang Embankment, the Beijiang Embankment, and the Huaihe Embankment, have all been damaged due to piping. Especially in the middle and lower reaches of the Yangtze River, the sp...
