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 article describes the use of geomechanical model to study the stability of the Three Gorges ship lock. This includes using two-dimensional planar geomechanical model to study the effect of double-line shiplock excavation on stability of lock slope under the influence of self-weight and in-situ stress and using 3D geomechanical model to study the most unfavorable operating conditions: weight, water Under the action of pressure and gate thrust, the stability of the two-lane shiplock pier was verified. In addition, the stability of the pier at 60m was verified, which provided the basis for the optimal design. This article also briefly describes the characteristics of the geomechanical model, its key technologies, and the social and economic benefits of this project.
