Based on the practical problems in the geological modeling of rail transit engineering in Chongqing, this study conducts a comparative analysis of the commonly use methods of engineering geological modeling. In view of the special geological conditions such as sand-mudstone interbedding and lens in mountainous cities, the problem of unified stratification of complex strata is solved by means of three-dimensional auxiliary layering and a process of three-dimensional modeling suitable for regular underground running tunnels and deep-buried underground running tunnels in mountainous cities is established.
