[0079] Example: such as figure 1 Shown, a kind of landslide seepage line and thrust optimization calculation method during reservoir operation period, the implementation steps of the present invention are:
[0080] Step 1. Obtain the reservoir water level fluctuation curve. For example, for the Three Gorges reservoir area, through years of monitoring the water level line, the reservoir water level fluctuation curve for the past ten years since the 175-meter impoundment can be obtained, and further according to the key characteristic points of the reservoir water level fluctuation curve, Generalize the generalized curve of reservoir water level fluctuation for many years, such as figure 2 shown.
[0081] Step 2. The calculation parameters of the landslide can be obtained by collecting survey reports, field surveys and tests. For example, the large hydraulic landslide on the bank of the Three Gorges Reservoir-Taping landslide in this embodiment, the engineering geological par...
