Abstract: Information design in engineering geology (IDEG) is a new extension of engineering geology and is of very great significance for optimum design of rock and soil engineering. According to theoretical research and engineering practice, we put forward some theories of IDEG in this paper. The principles and methods of IDEG are introduced and the working steps of information design are deduced. The techniques used in information design, i. e., the network simulation of fractures in rock mass, numerical simulation and geophysical information system (GIS) and key technique are discussed systematically. Finally, taking Dawu slope engineering of Jingzhu highway as an example, we have introduced the process and the steps of IDEG in detail, which shows that IDEG has many advantages in engineering operation.
