Taking the mud-bearing breccia gravel of a landslide in Fujian as an example,the shear strength parameters were obtained by in-situ direct shear test method.The appropriately modified parameters are used to calculate the landslide stability and get the stability coefficient of 0.971-1.129,which is basically consistent with the on-site landslide state,and is more accurate than the inverse calculation coefficient of 0.950-1.050.The in-situ direct shear test method is adopted to obtain the shear strength parameters of the landslide body with large particle size such as breccia gravel,which can make the treatment design more reasonable.
