This invention discloses a method for constructing lateral side openings in TBM tunnels under complex geological conditions, aiming to solve the technical problems of poor safety and low efficiency in traditional construction methods under complex geological conditions. Before constructing the side opening, a three-dimensional geological model is built and a warning threshold is set. When the detected data exceeds the warning threshold, an alarm is triggered and construction parameters are adjusted. A folding sliding track equipped with excavation equipment is deployed near the TBM equipment on the side of the side opening to be excavated. Small guide pipe holes and anchor bolt holes are drilled along the outer side of the excavation outline at the designed opening location of the side opening. After installing a double-section H175 steel arch frame optimized by finite element topology, shotcrete is used to seal and form a locking structure. Once the locking structure reaches the design strength, the side opening is excavated from the inside of the locking structure using a partitioned-step coupled excavation algorithm, and unbonded anchor cables are installed at the edge arch of the excavated side opening area. This method makes the excavation of side openings in complex geological environments extremely safe and efficient.
