Discussion on Project Objective Optimization Management of Petroleum Pipeline Investigation Enterprise;

The means was applied in the tunnel engineering of the Tongnanxuan freeway,its availability was confirmed in tunnel exploration,and the several problems were discussed in shallow seismic refraction exploration,and also bring forward some advice about it.

Basic principles and techniques for the shallow seismic refraction wave method and the high-density resistivity method are described in this paper in combination with engineering practice to explain the results of the refraction wave method and the high-density resistivity method in railroad and highway tunnel exploration.

With the rapid development of the road building, 3D GIS gets more and more extensive application not only in road reconnaissance design, but also in the plan of city road.

From the method principle of the transient electromagnetic method,combining function of the equipments,the paper describes the fieldwork method and technique,the method of data explain and the main regulation of magnetism source transient electromagnetic method to the railway tunnel exploration.
