In determining the calculation depth of the pile foundation settlement, the former code uses the stress control method, while the latter code uses the deformation control method. The determining methods of the calculation depth of pile foundation settlement of two codes were analyzed, while the difference and the deficiencies in determining the calculation depth of pile foundation settlement by using both methods were pointed out.Keywords: physical deep foundation; pile foundation; layer-wise summation method; calculation depth of settlement作者簡(jiǎn)介：朱國(guó)祥，碩士，教授級(jí)高工，Email：ZGX851@126.com。
