Introduction  The result of tower foundation configuration directly affects the accuracy and rationality of the foundation scheme. The problem of slow manual configuration speed and low accuracy of tower height-low leg need to be solved.

  Method  This paper analyzed the configuration process and configuration result,and then this paper put forward the problems in the manual configuration process. The accuracy of manual configuration was low, especially for towers with steep terrain or large slope ratio. The manual configuration results may affected the safety of foundation or caused the foundation design parmeters to be conservative. Through the problem analysis of the conventional configuration process, a reverse configuration method and a 3D configuration program were put forward in this paper.

  Result  The reverse configuration method is used to configure the same tower, and the result of the reverse configuration method is accurate, which can quickly and accurately calculate the various parameters and accurately calculate the actual exposed height.

  Conclusion  The accuracy and efficiency of reverse configuration method are better than that of manual configuration, and the configuration results are intuitive and accurate. It is recommended to use the method to configure the high-low leg in engineering.
