新建隧道下穿既有运营地铁线施工过程中极易对既有运营地铁线产生不利影响,而广泛采用的超前预注浆尚处于以经验性选取注浆施工参数的阶段,导致工程事故频发。为此,首先以开挖段地层物性参数、地层位移变化值作为输入层,注浆施工参数为...展开更多 新建隧道下穿既有运营地铁线施工过程中极易对既有运营地铁线产生不利影响,而广泛采用的超前预注浆尚处于以经验性选取注浆施工参数的阶段,导致工程事故频发。为此,首先以开挖段地层物性参数、地层位移变化值作为输入层,注浆施工参数为输出层,构建了基于BP(back propagation)神经网络的注浆施工参数预测模型;其次,以MAPE(mean absolute percentage e...
