摘要
物理模型试验是解决复杂岩土工程问题非常有效的一种方法,基于管幕预支护结构,介绍了物理模型试验设计方案的相似理论,分析了模型试验箱的设计、结构模型的确定、模型试验材料的选取以及试验实施与数据分析,指出了模型试验过程需注意的事项,通过具体的模型试验实例,对不同的问题时行了阐述,总结分析了管幕预支护结构模型试验的相关研究内容,提出了管幕结构模型试验需进一步研究的问题,并有针对性地提出了意见及建议。
Model test is one of the effective tools to resolve the complicated geotechnical engineering problems.An analog theory in the model test is discussed in the paper in order to perform the physical model test for the application of hollow anchor curtain as the pre-support in the tunnel excavation.The model test box design,model structure determination and the model test material composition and the test procedure and the data acquisition are evaluated and the key procedures in the tests are also introduced.This paper presents the technical details of the model test of using the hollow anchor curtain as the pre-support in the tunnel excavation.The model testing items are summarized and the problems that need further study are also suggested.
