Abstract The calculation of the surrounding rock pressure of shield tunnels in compound strata is still controversial currently. Aiming at the problems of the calculation of the surrounding rock pressure in compound strata by the classic modified routine method，load calculation models of shield tunnels for two cases of the upper-soft and lower-hard mixed soil ground and the upper-soil and lower-rock mixed ground were proposed，and a formula for calculating the active earth pressure in the lower part of the mixed soil ground was derived based on the slip-line theory. Comparisons were conducted among the results of the proposed method，the modified routine method and in-situ tests against the above two kinds of typical compound strata. The results show that the passive reaction acting on the bottom of tunnels is exaggerated by the modified routine method，which leads to unrealistic surrounding rock pressure，upward deformation and greatly different internal force compared with the measured results at bottom. However，the calculation results of the surrounding rock pressure，tunnel deformation as well as the distribution and the value of the internal force by the proposed method in this paper are in good agreement with the in-situ test results. The proposed method can provide reference for the design and research of shield tunnels in compound strata.

Key words： tunnelling engineering shield tunnel compound strata surrounding rock pressure calculation slip-line theory in-situ tests
