用地质力学模型试验方法研究坝基稳定性最有代表性且又最复杂的课题是复杂地基上的拱坝坝肩稳定性问题。我们曾为龙羊峡工程做了四个同比例拱坝整体结构模型试验。其中两个是天然地基和加固处理地基的整体地质力学模型试验(简称稳定模型)。由于该工程坝基地质构造的复杂性实属少见。同时我们做的模型相对较大。所以碰到过许多技术难题。下面介绍的系笔者通过实践总结出来的一些经验和看法,提供同行讨论。
The most representative and most complex topic for studying the stability of dam foundations using geomechanical model test methods is the stability of arch dam abutments on complex foundations. We have done four overall structural model tests for the Longyangxia Project. Two of them are the overall geomechanical model tests (abbreviated as stable models) of natural foundations and reinforced treatment foundations. Due to the complexity of the dam foundation geological structure of this project is rare. At the same time, our model is relatively large. So encountered many technical problems. The following describes the author’s experiences and views summarized through practice and provides peer discussion.
