Abstract: In order to respond to the call of national environmental protection, a large number of coal storage shed projects in coal mines have started construction, and pile foundations with large horizontal bearing capacity have been more and more widely used. The calculation formula of the characteristic value of the horizontal bearing capacity of pile foundation is put forward in the code. There are many influencing parameters. How to choose the value of each parameter has always been the key and difficult point in the design of this type of pile foundation. In this paper, the eigenvalues of the horizontal bearing capacity of single pile under the influence of different parameters are calculated, the results are analyzed and compared, the influence scope and development trend of each parameter are summarized, and the calculation results are checked with the single pile horizontal static load test of a specific project. Finally, some concrete construction measures are put forward to make the horizontal bearing capacity of pile foundation play a more full role, and then the results are generated. Better Economic Benefit.
