摘要
以施工期坝体沉降为研究对象,在以往沉降规律研究基础上,从蠕变角度出发,确定了施工期沉降监测模型结构,确定填筑影响下与时间相关及与时间无关的2类模型因子。同时在该模型的基础上,借鉴传统的经验模型,提出了一种简单合理的因子形式。并以实测资料分别建立了统计监测模型,经过验证,表明这2种模型对于模拟和预测施工期土石坝的沉降是行之有效的。
This paper studies the settlement of the earth and rockfill dam in the construction period. Based on previous studies
of the regularities of settlement, a settlement monitoring model is set up from the angle of creep, and two kinds of model
factors, which are time-related and time-unrelated, are determined. On the basis of the model and traditional empiric model, a
new model with simple and rational factors is developed. The above two types of models have been verified with a statical model
built with monitoring data. It has been proved that the two models are effective in simulating and predicting the settlement of
the earth and rockfill dam in the construction period.
