摘要: 針對(duì)水壓-溫變-時(shí)效(hydraulic-seasonal-time,簡(jiǎn)稱HST)模型監(jiān)控高拱壩變形的不足,以變形規(guī)律相似的測(cè)點(diǎn)群為對(duì)象,搭建一種新的監(jiān)控模式。首先,依據(jù)面板數(shù)據(jù)格式,建立水壓、溫變和時(shí)效面板模型;其次,引入固定效應(yīng)(fixed effect,簡(jiǎn)稱FE)和隨機(jī)效應(yīng)(random effect,簡(jiǎn)稱RE)表征個(gè)體差異效應(yīng),據(jù)此構(gòu)建HST-FE/RE面板模型;然后,...
