【摘 要】:為解決常規(guī)沉降監(jiān)測不能較好反應深層土體變形特點這一工程難題,以實際工程為例,采用土體分層沉降儀對盾構(gòu)穿越重大風險源時深層土體進行監(jiān)測,并對測點標準化、控制值制定、數(shù)據(jù)銜接等問題提出合理化建議。

【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.
【Key words】:subway; shield tunnel; soil layers;settlementmonitoring
