Abstract: With the application of anode protection technique for the deeply buried pipeline, it is always helpless to use the method of shallow anode bed, so that it is necessary to use deep anode bed to achieve optimum result. Because deep anode bod is the permanent facility, careful consideration should be paied to the rationality and the stability of its structure, and to the insulating treatment of its components etc. The paper introduces the above mentioned problems in design and points out that its installation should be away from unstable regions too.
