APM system in Zhujiang New Town of Guangzhou is the first APM line designed by domestic institute. Problems prone to occur during the design and construction of APM system are summarized and discussed on basis of design, construction and operation experience. Conclusions drawn are as follows: 1) Rational structural heights should be selected for tracks in circular tunnels; 2) Rational guide rails and guide rail supports should be designed, so as to improve the manufacture precision and the adjustability of the track structure; 3) Measures to improve the durability and repairability of the surface layer of running tracks should be further studied; 4) Relevant discipline interfaces should be carefully coordinated.
