The invention relates to a city underground engineering catastrophic monitoring simulation system. The system comprises a sand table and a multi-module data display device, wherein the sand table comprises a model road, a model tunnel, a model slope and a model track, the model road, the model tunnel, the model slope and the model track are correspondingly provided with monitoring modules, and each monitoring module is connected with the multi-module data display device through the wireless network or a data line. The system is advantaged in that city underground engineering catastrophic monitoring can be dynamically simulated, all-round catastrophic monitoring of underground engineering of areas simultaneously having complex conditions such as roads, track traffic, tunnels and mountain slopes can be especially dynamically simulated, monitoring data can be timely acquired, and city underground engineering catastrophic and mutual influence in various types can be visually and dynamically demonstrated conveniently and effectively.
