Abstract:An attempt was made to establish an assessment system for subsurface karst development by combining quantitative and qualitative methods. The assessment results can assist the preliminary determination of the extent of underground karst development and guide the planning and construction of underground engineering projects. Firstly, the major factors influencing the karst development were selected as the assessment indices in the system, and the varying degrees of subsurface karst development are defined. Then, the weights of these assessment indices were determined using a synthetic weighting method, in which the fuzzy hierarchy analytic process determines the qualitative weights, while the quantitative weights were determined by a sensitivity analysis of the Bayesian belief network. The Fuzzy Analytic Hierarchy Process was used to determine the ratings of the karst development states in the assessment indices. Moreover, based on the statistical data, the quantitative assessment results belonging to each degree of karst development were determined by comparing the calculated assessment results with the real karst development status. The proposed assessment system was applied to a railway tunnelling project in China to evaluate the degree of surface karst development before tunnel construction. A comparative analysis of the assessment results with the recorded results shows that the assessment of the tunnel zone, accounting for 97.1% of the total tunnel length, is consistent with the recorded results. Assessment errors only occur in 2.9% of the tunnel zone, where the degree of karst development was assigned as "developed", while the records indicated it was "extremely developed". However, the quantitative assessment result of the karst development degree is 0.69, which is close to the value range of "extremely developed", 0.70-1.00. As this minor error is acceptable in the preliminary assessment of the degree of karst development, the proposed assessment system is verifiably reliable.
