| 摘要:湿蔗渣堆场输送斜栈桥为储运系统的关键设施，针对现行规范缺少蔗渣堆侧压力、推土机荷载取值标准，本研究结合文献查阅、现场调研，系统开展研究，明确湿蔗渣等效堆积密度应取800 kg/m3，静止侧压力系数K0=0.2，得到推土机附加荷载与撞击荷载的简化计算方法。同时，梳理易忽视问题，如最不利堆积工况选取、斜栈桥因支撑柱刚度不均易引发内力累积及温度应力集中、斜栈桥上下部结构分开设计的隐患、强酸性腐蚀防护等，通过现场调研与数值模拟，提出节点构造优化、防腐体系升级等工程对策，以期为蔗渣堆场斜栈桥的安全设计提供技术参考。 |
| Abstract:The inclined conveyor gallery for wet bagasse piles is a critical facility in the storage and transportation system. Addressing the lack of current standards regarding lateral thrust from the bagasse pile and loading criteria for bulldozers， this paper through literature review and on-site investigations， systematically defined the equivalent bulk density of wet bagasse as 800 kg/m3， and the lateral earth pressure coefficient as 0.2. It proposed simplified calculation methods for additional loads and impact loads caused by bulldozers. Meanwhile， it identified often-overlooked issues—such as selection of the most unfavourable stacking conditions， potential internal force accumulation and temperature stress concentration due to uneven support column stiffness， risks associated with separate design of upper and lower structures in the inclined conveyor gallery， and protection against strong acidic corrosion—and offers engineering solutions including optimized node construction and upgraded anti-corrosion systems based on field surveys and numerical simulations， aiming to provide technical references for safe design of inclined bridges in bagasse yards. |
