摘　　要：以实际工程为例,通过对冻结孔布设参数分析,推导出了长度和倾角等冻结孔布设参数与透视图中相应参数的换算公式,得出了冻结孔布设参数间的相关变化规律。同时,提出了冻结孔参数化模型的建立方法,建立了相关参数的三维可视化冻结孔布置模型,经碰撞检测分析与冻结帷幕形成效果预测分析,验证了冻结孔布置模型的兼容性和可靠性,提高了其效率和质量,为复杂空间条件下的冻结孔位置设计提供了经验和思路。Taking the actual practice as the example,with the parameter analysis on the freezing hole layout,the conversion equation between the length and inclination and other freezing hole layout parameters and the corresponding parameters in the perspective drawing was inferred.The related aviation law between the layout parameters of the freezing hole was obtained.Meanwhile the establishing method for the parametric model of the freezing hole was provided and the 3 D visualized freezing hole layout model of the related parameters was established.With the collision detection analysis and the predictive analysis on the formation effect of the freezing curtain,compatibility and reliability of the freezing hole layout model was verified and the efficiency and quality were improved.All above could provide the experiences and idea to the location design of the freezing hole.
