        If we talk and discussion about kinematic analysis, it will be closely related to be discontinuity in the form of joint, fault, shearzone, bedding plane, unconformity/transition, foliation/schistosity. There are 4 types of failure in slope, circular, topling, wedge, planar. The different of slope failure (circular) due to material characteristic (soft) commonly occurs in  disposal in uniform materials. Probability of failure can be analyzed utilize rocscience dips (slope) and unwedge (tunnel).       

Picture 1. Type of slope failure

        Kinematic analysis utilize to define type of failure occuring in tunnel. Identifikasi potensi runtuhan berdasarkan WI (Work Instruction) yang didasarkan oleh Pratama et al. (2015) diklasifikasikan menjadi 4 jenis, Wedge, Blocky, Slabbing, and Squeezing.
