Abstract: Under the complex soil and rock geological and geotechnical conditions, both the bearing and deformation characteristics of the rock socketed slurry wall are significantly different from those conventional slurry walls. This paper presents a case history of construction monitoring of a rock socketed slurry wall in Suzhou Metro No.3 Line project. The paper evaluates the construction monitoring data for the rock socketed slurry wall under different construction, geotechnical conditions and various supporting conditions. The deformation of this rock socketed slurry wall is summarized and the depth into the rock socket could therefore, be optimized for the future similar projects.

Key words: complex stratigraphy, rocket socketed slurry wall, deformations, construction monitoring
