摘要
Data of investigation of the Huangtupo landslide and the Baitupo deep-monitoring borehole core data are analyzed by comparison in this paper and it is found that the weak interlayers in the upper submember of the third member of the Badong Formation have developed more densely than those in the lower submember,and interpenetrant interlayers have developed in the sliding bed of Huangtupo landslide.Interlayers have been mudded into the type of gravel clay.The original rock structure of the Huangtupo landslide is recovered according to the weak interlayers’ distribution characteristics in the third member of the Badong Formation,from which it can be concluded that the Huangtupo landsilde is the product of many times’ sliding of compound retrogressive landslide.
