Research purposes： Compared with the all kinds of arrangement sets of geophysical prospecting, the discussion is made on the survey method for the three dimensional shape of geological disaster, and taking Nancun Tunnel construction of State Highway 108 as an example, the introduction is given in details to the working method, equipments and real field results of geological forecast in advance with synthetic parameters. Research conclusions：From the discussions on the spatial method and technology for geological forecast in advance with synthetic parameters and the simulation tests and field tests of USEP21 Integral forecast device, it is concluded： （ 1 ） The perfect synthetic parameters for the geological forecast in advance for tunnel construction under the complicated geological condition are wave velocity plus resistivity. （2） According to the characteristics of underground engineering, a series successful test achievements have been made by USEP21 Equipment which has bright future of being used in tunnel construction and underground engineering because it is rather adaptive to small space. （3） Application of the synthetic parameters, and the technology, method and theory of the spatial is an inevitable trend of geological forecast in advance. （4） The spatial multi component survey device of angle displacement is the most perfect means of geological survey in advance for underground engineering.
