Construction method for muddy water large shield to pass through metro depot with low influence

The invention relates to the technical field of shield construction, in particular to a construction method for a large-muddy-water shield to pass through a metro depot with low influence. The construction method comprises the following steps that S1, the integrity and the settlement degree of a structure foundation are explored, and risk assessment of shield tunneling machine underneath pass construction is conducted; s2, reinforcing and repairing the structure foundation according to the evaluation result; s3, dividing a test section for underneath pass construction of the shield tunneling machine, collecting and analyzing parameters of settlement and structural stress change of a structure of the test section in the construction process, and determining a construction scheme of underneath pass construction of the shield tunneling machine according to an analysis result; s4, formal shield tunneling machine underneath pass construction is conducted according to the construction scheme of shield tunneling mac
