Abstract


Settlement and deformation of marine soft soil under the heap loads often is a key link in the dike construction and reclamation from the sea land reclamation and other major projects . In order to study the sea soft soil deformation characteristics , in the experiments of the indoor unit on the basis of improved soft soil model by the modified Cam-Clay joined the inherent structural characteristics of marine soft soil . Combined with the actual project , establish the numerical analysis model of large area uniform the heap load and new seawall uneven loads sea the soft soil long-term settlement and the excess pore water pressure dissipation characteristics , the analysis consider the shaft foundation treatment and seawall filling process . By comparison with in situ monitoring data reflect the seawall below the factory area backfill at foundation settlement and lateral deformation of the model simulation , at the same time consider the foundation at different depths in the filling process Office of excess pore water pressure accumulation and dissipation processes . New seawall marine soft soil generally larger work after long-term settlement , followed by the tunnel boring Shield Tunnel longitudinal deformation cause uneven settlement seawall larger work , seriously jeopardize the safe operation of the tunnel . How do you measure calculated in the case of soft soil tunnel safety critical engineering problems . Of the shield construction seawall settlement measured data conducted in-depth analysis , and key tunnel cross-section subsidence in situ monitoring . Settlement distribution obtained at the tunnel , curve fitting obtained tunnels curvature ; equivalent continuous model to calculate the longitudinal stiffness of shield segment , by the stress analysis to find out the tunnel curvature and deformation , cracks relationship analysis of the stress state of the tunnel , foundation treatment recommendations to solve critical engineering problems .
