Application of Type Ⅳ Lassen Steel Sheet Pile Combined with Anchor Rod Support in Bridges
The foundation construction conditions of bridge engineering are complex and the safety requirements are high.In order to meet the demand of half widthconstruction and half widthtraffic,a design scheme combining type Ⅳ Lassen steel sheet pile occlusion and anchor rod support is proposed.On the basis of mechanical analysis and stability evaluation,the node design of pile connection and anchor bolt anchorage are optimized to enhance the connection stiffness of pile anchor system.The simulation results show that the o-verall mechanical property and tensile strength of the steel anchor support structure is improved by 127 MPa,and the maximum dis-placement of the soil is controlled within 3 cm.
