Study on Instability Mechanism of Super-Deep Anchorage Foundation Pit Slope of Tertiary Strong Weathered Basalts

Abstract:

Taking the anchor foundation pit of the super-large highway bridge in Yunnan as an example, the stability is studied. Based on the stratum characteristics of the tertiary strong weathered basalts (TSWB) and analysis principle of engineering geology，many aspects including topography and geomorphology, geological structure, geotechnical interfaces, structural characteristics, geotechnical parameters are considered to analyze the engineering geological environment of the foundation pit. Then, the qualitative analysis of stability and possible instability mode are made.
