摘要
考虑堆石体沉降的影响因素,推导了填筑分量和时效分量的数学表达式,给出了面板堆石坝 施工期沉降二维时空分析模型的一般表达式,并利用沉降实测资料验证了该模型的合理性。
Considering the factors influencing the rockfill settlement, the mathematical expressions of fill-up component and time effect component are derived. The general expression of the two-dimensional space-time analysis model for the settlement of CFRD in the construction period is presented, and the rationality of the model is validated based on observed data.
