【摘    要】：為解決常規(guī)沉降監(jiān)測(cè)不能較好反應(yīng)深層土體變形特點(diǎn)這一工程難題，以實(shí)際工程為例，采用土體分層沉降儀對(duì)盾構(gòu)穿越重大風(fēng)險(xiǎn)源時(shí)深層土體進(jìn)行監(jiān)測(cè)，并對(duì)測(cè)點(diǎn)標(biāo)準(zhǔn)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

地鐵盾構(gòu)掘進(jìn)過程中需要穿越不同地層、建（構(gòu)）筑物、河流等眾多重大風(fēng)險(xiǎn)源，科學(xué)開展沉降監(jiān)測(cè)工作對(duì)隧道安全具有重要意義。（剩余4451字）
