摘要
针对南水北调中线总干渠某高填方渠道现场工程质量控制问题,采用双曲线法和三点法对高填方渠道的工后沉降进行预测。结合三点法引入双曲线法模型,提出了基于双曲线模型的三点法,并将其运用到高填方渠道的沉降预测分析中。通过与沉降观测数据综合对比分析,发现基于双曲线模型的三点法预测效果最好,为研究高填方渠道沉降提供了新的分析途径。
Aiming at the quality control of a high-filled main canal section of Middle Route Project of South-to-North Wa-ter Diversion, settlement of high-filled canal after construction is predicted by using hyperbola and three-point methods. In this paper, three-point method based on hyperbolic model is established and applied to the predictive analysis on settlement of high-filled canal. Through a comprehensive comparative analysis of settlement observation data, it is found that the result is the best by using the three-point method on the basis of hyperbolic model, and it provides a new analyzing way of research on settle-ment of high-filled canal.
