Abstract Research purposes:China′s metro construction presents the trend of geological environment complexity, so it is urgent to solve the problem of metro tunnel shield equipment selection under complex geological conditions. It is required to establish the selection principles according to the hydro-geological environment for shield/TBM dual-mode excavation equipment, while proposing a correction function for the interval mode of both project duration and cost. Based on the interval tunnel project of Shenzhen Metro Line 14, this paper analyzes the actual tunnelling speed of TBM and earth pressure mode in micro and medium weathered stratum and verifies the adaptability of dual-mode shield tunnelling in the composite stratum.
Research conclusions:(1) For the selection of dual-mode shield/TBM based on geological conditions, it is necessary to determine whether to select dual-mode according to the difference of stratum parameters and determine the section mode by the selection principle of single-mode shield, while considering other adverse geological conditions along the line. (2) The proportion of hard rock, soft rock uneven section and soft soil section in the whole section of the Buji-Shiyaling section of Shenzhen Metro Line 14 is 5 ∶3 ∶2. Combined with the selection principle of shield/TBM, it is suggested to adopt the earth pressure/TBM dual-mode shield TBM. (3) Based on the construction period and cost, the limit length of the transition of the slightly and moderately weathered strata is determined, and the section mode is modified. (4) The research results can provide the specific processes and methods for the selection of shield /TBM dual-mode tunneling equipment in metro tunnel.

Key words： tunnel engineering composite stratum dual-mode shield/TBM mode selection tunneling adaptability
