Abstract Based on in-situ monitoring and analysis of one metro project in Hangzhou, segment floating can be divided into primary floating and secondary floating with the primary floating taking up a larger proportion, from 50% to 80%. Combined with shield construction at this section, Abaqus finite element software was applied to analyze the segment floating in soft soils. Results show that segment floating is divided into three stages: the surging stage, the gentle development stage, and the stabilizing stage. Additionally, the laws of segment floating, along with the resilience of underlying soils at the segment bottom and settlement of overlying soils on the segment top varying with the grouting pressure, grout elasticity modulus, earth pressure in the soil chamber, and jack pressure were obtained.
