高堆石坝施工过程复杂,其施工进度受到诸多因素的影响,难以进行实时控制。本文在对高堆石坝施工进度影响因素全面分析的基础上,提出了基于实时监控的高堆石坝施工进度影响因素实时分析方法。通过运用基于GPS技术的实时监控系统,实时地提取重要的工程信息以及施工参数,并分析其内在规律,将其结果与堆石坝施工系统仿真中的相应参数进行比对,建立多元线性回归模型分析各影响因素与施工进度的相关性,并通过工程实例证明该方法为堆石坝施工进度的实时控制提供了分析手段和科学的决策依据。
Construction progress of high rock-fill dam is complicated and can be affected by many factors, which leads to difficulties in real-time monitoring. This paper describes a real-time analysis method based on real-time monitoring to examine the influencing factors of construction progress of high rock-fill dam. In this method, the important engineering information and construction parameters are real-timely obtained and the inherent laws are analyzed using a GPS-based real-time monitoring system. These parameters are compared with those calculated by system simulations of the same construction progress, and a multiple linear regression model is developed for analysis of the correlations of the influencing factors with the rate of construction process. Application to a case study of real project shows that the method provides a useful tool and a basis for real-time control of construction progress of high rock-fill dams.
