地下粮仓结构设计研究现状及选型关键问题浅析

Simple discussion on research status and form selection of underground granary esign

现有地下粮仓形式多样,如何正确合理选型并对其进行结构设计成为推广应用地下储粮技术的关键。本文以钢筋混凝土地下粮仓为对象,指出:采用理论推导与有限元分析相结合的研究方法,在考虑贮料荷载、土压力,地下水压力共同作用的前提下,对仓型的选择和优化问题进行研究,需解决荷载计算及荷载效应组合、结构设计的有限元法、仓顶、仓壁及仓底结构选型等一系列关键问题。

Existing underground granaries are in various forms. How to select form and design structure is the key of promoting the application of underground grain storage technology. This paper focuses on the reinforced concrete underground granaries and presents that combining theoretical derivation and finite analysis methods, considering the loads such as grain load, soil pressure, groundwater pressure, there are many problems of research on the form selection and optimization. The series of key problems are the load calculation and load effect combinations, the finite element method of structure design, the form selection of top of silo, silo wall and bottom of silo.
