Geological conditions play a leading role in the duration and cost of underground projects. It is of great significance for contractors involved to study geological risk management. In view of this, based on underground projects, the author introduces the concept of schedule deviation, quantification of the engineering geological risk, determination of three evaluation indicators of engineering geological risk and the establishment of matching contract adjustment mechanism. Contractors and owners can take advantage of it to divide the right of schedule adjustment, to divide and quantify the attribution of geological risk. By empirical analysis of foreign project cases, engineering geological risk can be divided, quantified and allocated through contract adjustment mechanism.
