Aiming at the problem that the uneven settlement and deformation of soft soil foundation cause the poor adaptability of belt conveyor and trestle structure,we study the integration of belt conveyor and trestle structure,compare various structural sections and truss forms,and optimize to achieve the lightest weight and excellent adaptability of foundation settlement.The results show that the trestle with no vertical web member and no top lateral bracing is the lightest trestle structure,which can adapt to the settlement of foundation by combining with the inverted herringbone pillar and mechanical structure.The achievement can provide references for the similar projects.
