不同施工过程对船闸闸首底板应力影响的仿真模拟分析

Simulation and Analysis of the Stress Influence of Lock Gatefloor by Different Construction Process

在通常情况下,船闸闸首结构底板应力的大小及分布不仅与结构的最终状态有关,而且还与结构的施工过程有关。运用非线性有限元分析方法,考虑不同材料之间的相互接触作用,仿真模拟不同施工过程对船闸闸首结构混凝土底板应力大小及分布的影响。研究成果可供混凝土船闸设计、施工时参考。

In general,the value and distribution of stress in lock gate floor are related to not only the terminal state, but also to the constructing process. In this paper, using the method of nonlinear finite element and considering the contact between different materials, the influence of different constructing process on stress is simulated. The results can be used for the design and construction of concrete lock.
