全强风化花岗岩地层海底隧道注浆效果检测

Grouting effect test analysis in fully-heavily weathered granite ground of sub-sea tunnel

针对厦门翔安海底隧道左线F4风化槽中全～强风化软弱地层的水文地质与工程地质情况,采用全断面帷幕注浆技术注浆后进行检测,详细论述注浆效果检测的4种有效方法,为类似地层注浆设计与施工、注浆机理分析、注浆效果监测提供可靠依据。

Aiming at exist fully-heavily weathered ground in left lane of Xiang＇ an sub-sea tunnel in Xiamen, this paper presents the hydro-geological and engineering geological conditions of F4 weathered slot aimed at this layer. It uses technology of the full-section curtain grouting and in detail expounds four effective ways to detection grouting effect. It can provide a reliable basis for the design and construction of grouting, and grouting mechanism analysis and detection grouting effect in similar formation.
