“装配式钢筋混凝土管形通道”的结构型式和受力条件相对复杂。采用过程计算的方法,针对结构特点、技术标准、施工方案和施工流程,制定了计算阶段和计算项目,明确了各验算状况、作用效应组合的对应关系及相关系数取值。鉴于目前对此类结构体系的计算理论和计算模型研究还不尽深入,提出基于弹性初始状态的“有限元m法”计算方法和土压力动态计算方法,建立结构与土体联合作用体系计算模型并编制相应计算软件。通过模拟施工和使用阶段的通用结构计算及其状态验算,验证了结构设计的安全性。
“Assembled reinforced concrete tubular channel ” structure type and stress conditions are relatively complex. Using the method of process calculation, the calculation stage and calculation items are formulated according to the structural features, technical standards, construction scheme and construction process, and the corresponding relationship and the correlation coefficient values of each checking condition and effect combination are clarified. In view of the fact that the research on the calculation theory and calculation model of this kind of structural system is still incomplete at present, this paper proposes the calculation method of “finite element m method” and dynamic calculation method of earth pressure based on the initial state of elasticity and establishes the joint action system of structure and soil Calculate the model and compile the corresponding calculation software. Through the simulation of construction and use of the general structure of the calculation and status checking, verify the structural design of the safety.
