摘要
本文阐述采用地质力学模型研究三峡船闸的稳定问题。其中包括用二维平面地质力学模型研究在自重和地应力作用下,双线船闸的开挖对于船闸边坡稳定的影响,及用三维地质力学模型研究在最不利的运行工况:自重、水压力、门推力作用下,双线船闸中隔墩的稳定;特别验证了60m中隔墩的稳定,为优化设计提供了依据。 本文还简单叙述了地质力学模型的特点,它的关键技术、及本课题的社会、经济效益。
This paper studies the stability of the ship lock of Three Gorges project by using geomechanical models. These include a two-dimensional model and a three-dimensional model. The former studies the influence of excavation of double line ship lock on the stability of the slope under the action of gravity load and crustal stress. The latter studies the stability of the rock mass between two ship lock lines in the most unfavourable conditions, i. e. , under the action of gravity load, water pressure and the pressure of lock gate.Test results show that the 60 metre dividing pier between lock lines is stable and provide important basis for the optimization of the design.This paper also presents the characteristics and key techniques of making of geomechanical models as well as the social and economic benefit of the special subject.
