混合式闸墙与基岩间的非线性接触分析

Non-linear Analysis on Contact Area Between Lock Chamber and Foundation Rock

针对广西西津船闸闸墙的结构布置,采用连续介质非线性理论和有限元法,建立数学模型,分析了衬砌墙墙体与基岩之间的接触状态和接触应力,揭示了墙体与基岩应力分布的基本规律,对基岩上闸墙体型的优化设计提供了参考。

For optimizing the structural layout design of the lock chamber in Xijing project, the theory of continuum mechanics and 3D non-linear FEM are used to model and analyze the contact conditions and contract stress between lock chamber and foundation rock. The basic law of stress distribution on the chamber and rock is revealed, which is a reference for the optimal design of chamber structure.
