Abstract: Aiming at the existence of severe seepage disease in Buddha Bay of Baoding Mountain, Dazu Rock Carvings, the technical methods of surface mapping, test boring(trenching),geological radar, high-density resistivity, drilling CT,digital borehole camera and pressure(injection) water test and so on were applied, the detailed exploration and tracking monitoring for engineering geology and hydrogeology conditions of the rock carving zone were carried out by stages, so the structural characteristics and hydrogeological characteristics of rock mass of Buddha Bay were found out, and the rules of development and distribution of fracture seepage network were revealed. On this basis, the in-depth analysis for the relative seepage patterns was conducted by using 3D GIS visualization and numerical simulation, so the scientific rationality of the exploration program was verified and the efficiency and accuracy of exploration was improved effectively. This research can provide a sufficient basis for the control of water hazard in Buddha Bay, and offer reference for geological exploration of similar projects.
