To analyze the influence of shield tunneling reception on the additional stress of work shaft enclosure structure， taking a shield work shaft as the supporting engineering， a calculation method for additional stress of work shaft enclosure structure caused by bulkhead additive thrust of shield cutter head， friction force between shield shell and soil， synchronous grouting pressure and soil loss was proposed by establishing mechanical model of work shaft enclosure structure in the shield tunneling reception period， based on Mindlin stress solution of elasticity mechanics and Sagaseta formula. The main influencing factors of the additional stress of the work shaft enclosure structure were calculated and analyzed， and the mechanical behavior of the work shaft enclosure structure during receiving period was studied by numerical simulation. The principle of the shield tunneling proximity control was formed based on engineering examples. The results show that： 1） the influence range of additional stress of work shaft enclosure structure increases with the increase of shield tunnel diameter and mainly occurs in the 1.5 times of shield diameter. The depth of the shield machine has an important influence on the maximum value of additional stress. 2） The total additional stresses are mainly caused by frontal additional thrust and friction between shield shell and soil， accounting for about 1/3 and 2/3， respectively. The additional stresses caused by synchronous grouting and soil loss are negligible when compared with the first two. 3） The theoretical calculation and numerical simulation results of total additional stress are basically the same， which verifies the reasonableness of the calculation method. At the same time， the numerical simulation shows that the bending moment and deformation of the enclosure structure of the working well during the receiving period of shield tunneling increase by about one time， which should be paid attention to in the receiving construction of shield tunneling. 4） Based on the calculation and analysis results of the additional stress of the work shaft enclosure structure caused by the excavation speed， the principle of “low speed” reception is adopted in the key receiving interval of the project （10-0 rings）， which ensures the safe receiving of shield and provides a reference for similar projects.
