Abstract

Abstract

The existing calculation theories of steel sheet pile were analyzed, and the soil pressure hydrostatic pressure, flowing water pressure, wave pressure and supporting pressure acting on steel sheet pile cofferdam were calculated.The construction process of steel sheet pile cofferdam was analyzed, the steel sheet pile was taken as nonlinear elastic foundation beam, the nonlinear differential equations of elastic foundation beam were established based on the incremental method, the horizontal resistance coefficient of foundation soil, the bending deformation coefficient of steel sheet pile and the increments of internal and external loads of steel sheet pile cofferdam were calculated, and the forces and deformations of steel sheet pile under all conditions were studied.Based on the steel sheet pile cofferdam of Yuxi River Bridge, the internal force, deformation, strength, overall stability, anti-overturning safety, anti-uplift safety of steel sheet pile cofferdam were checked.Calculation result shows that the maximum displacement is 38.12 mm and less than the specification value of 80mm; the maximum allowable stress of steel sheet pile is 168.60 MPa and less than the specification value of 218.52MPa; the maximum allowable stress of pipe pile is112.29 MPa and less than the specification value of 174.07 MPa; the overall stability safety factor of steel sheet pile cofferdam is 2.8and greater than the specification value of 1.3;the antioverturning safety factors under 4cases are 3.4, 2.8, 2.9, 1.9respectively and greater than the specification value of 1.2;the anti-uplift safety coefficients based on Prandtl theory and Terzaghi theory are 3.1, 3.5respectively and greater than the specification value of 1.6.Obviously, the safety calculation results of steel sheet pile cofferdam based on the incremental method meet the requirements of the relevant specification, so the calculation method is reasonable and reliable.
