Abstract：In order to accurately calculate the jacking force required for ultra-shallow buried rectangular pipe jacking under the dual influence of complex geology and supporting structure, the jacking force composition mechanism and influencing factors of rectangular pipe jacking in complex ultra-shallow buried strata were studied. Based on the large-scale pipe-rock friction mechanical property test experimental device, the contact friction characteristics of pipe joints sliding on different rock contact surfaces were analyzed. The main results are as follows: (1) Considering the influence mechanism of different strata and supporting structures on the friction resistance of rectangular pipe jacking, a calculation model of rectangular pipe jacking force suitable for rock strata and composite strata is proposed for the first time. (2) The rock strength, particle size and pressure of the contact surface have no significant effect on the friction coefficient of the pipe section sliding on the rough contact surface of the rock, while the friction coefficient of the contact interface will be significantly reduced after adding the anti-friction slurry. (3) The dry and wet friction coefficients of the pipe section in the medium weathered and slightly weathered granite strata can be taken as 0.719 and 0.629 respectively, and the dry and wet friction coefficients in the strongly weathered granite strata can be taken as 0.675 and 0.603 respectively. (4) Engineering examples show that the error between theoretical and measured jacking force data is less than 7 % in soft soil, soft rock and normal excavated rock strata, which confirms the accuracy of the jacking force calculation model and calculation parameters in this paper. The research results of this paper can provide an important basis for the calculation of jacking force in pipe jacking engineering in similar strata.
