【Abstract】:Inorder tosolvethe engineering problemthatthe conventional settlement monitoring can not reflect the change of deep soil well. In this paper, through engineering examples, the soil layer settler is used to monitor the deep soil when the shield traverses through major risk sources, and reasonable suggestions are put forward for standardization of measuring points, formulation of control values, data connection and other issues.
