In order to study the influence of seepage on high slope stability, the impact of drainage hole blockage on slope stability is analyzed by in-situ test technology, near-field photogrammetry and indoor test and numerical simulation.According to the groundwater monitoring of the water meter and pore pressure meter, when the drainage hole blockage exceeds 80%, the pore water pressure increases by about 13m, by 25kPa; is monitored by the steel gauge and anchor gauge. When the drainage hole blockage exceeds 80%, the shear force of the slope anti-sliding pile increases by 20%, about 30kN; analyzes the slope deformation by the near-view photography technique, when the drainage hole blockage exceeds 80%, and the slope deformation of 44mm, exceeds the slope deformation warning value of 30mm,.After theoretical calculation and numerical simulation analysis, the groundwater level and support structure under different blockage conditions. Numerical simulation results show that when the drainage hole is less than 60%, the supporting structure and slope deformation grow linearly, while when the blockage degree exceeds 80%, the support structure increases sharply, and according to the finite element strength, when the blockage degree exceeds 60%, the slope stability coefficient decreases sharply and the risk of instability.
