Thefailure, which was analysed and interpreted in accordance with the local geology, occurred in a slopecomprised of a limestone rock mass in the upper part and a claystone-sandstone sedimentary formation inthe lower part. The failure mechanism, which was interpreted as complex toppling combining toppling andcircular failure, was back-analysed using analytical and numerical techniques. 收起
