英文摘要	The soil-rock mixture landslide is a compound with complex surface topography and loose structure, of which the structure is difficult to detect, and there is no effective geophysical method to solve it so far. This paper documents the first application of the two-dimensional miniature-array microtremor profiling method to detecting the soil-rock mixture landslide in Baidian township, Hengyang City. The results reveal that the upper part of the landslide is a sandy clay layer containing lots of rocks and the under part is completely weathered granite with homogeneous lithology and less rocks. The upper interface of the granite layer is the potential sliding surface of this landslide. As the sliding surface is gentle in the middle but relatively steep in the trailing edge of the landslide, the risk of gravity instability and sliding in the trailing edge of landslide is high. With obvious fluctuations, the depth of the sliding bed (strongly-moderately weathered granite, slightly-non weathered granite) is more than 10m and its composing rock is relatively compact, complete, with good stability and not easy to slide. The results of this exploration are consistent with drilling data, providing valid basis for evaluating the stability of the landslide and designing a reasonable landslide treatment scheme.
