嵌岩灌注桩模型试验几何相似常数的优化设计

摘要

As one of important parameters in model test, model scale is the key to determine accuracy and reliability of model test results as well as model test cost. Suitable model scale is selected by optimizing design for geometric similar constant in the rock-embedded cast-in-place pile model test, which will provide the reference for further determining reasonable size and limit bearing capacity indexes of model pile.%模型比尺是模型试验的重要参数,决定了试验成果的精度、可靠性和模型试验的经费投入.通过对嵌岩灌注桩模型试验几何相似常数的优化设计,选定适用的模型比尺,为进一步确定模型桩的合理尺寸、极限承载力指标等参数提供依据.
