| Abstract: | This paper compares both merits and demerits of the calculating formula of Coulomb's earth pressure theory and Rankin's earth pressure theory, puts forward an improved earth pressure calculation method. By using two kinds of calculation models for single-layer pile-anchor supporting structure, this paper compares the influences of different calculation models on supporting structures' optimized calculation, discusses the effect of supporting position on the maximum moment on the pile and, through actual engineering examples, makes comparison of calculations, verifying the results of the optimization. |
