The Analysis of Stratum Settlement for a Large Diameter Slurry Shield obliquely Under-passing Embankment of The Yangtze River

Displacement caused by tunnel excavation soil may cause the deformation of the buildings or structures nearby and even cause disaster. On the background of a large diameter slurry shield obliquely Under-passing embankment of The Yangtze River. First of all, three dimensional finite element method is used to make a dynamic analysis of the embankment settlement. And the result is compared with the measured values, the accuracy of the finite element method was verified. Then, the stratum settlement of embankment is analyzed under different cross Angle and depth of tunnel. Some useful conclusions are drawn, which can provide some useful reference for similar engineering of tunnel under-passing embankment.
