Failure Mechanism and Mitigation Measures of the G1002 Electricity Pylon Landslide at the Jinping I Hydropower Station

Figure 4

Sliding zone of the G1002 EPL (towards southwest). The residual soil masses in the rear area of the main scarp indicated that the sliding source consists of silty clay, fine rubble, and gravel derived from silty slate. Residual soil masses covered with vegetation would fail by the retrogressive erosion of rainfall.
