Large span double-row steel sheet piles were constructed in marine environments to serve as cofferdams of dry dock projects. Due to the construction of the dock excavation, considerable deformation of the cofferdam could occur. The deformation of the large span double-row steel sheet piles was measured during construction of a large scale dock project in Shanghai. Extensive field performance data were collected including lateral survey data and lateral inclinometer data. Construction procedures were summarized and correlated with monitoring data. The measured data were analyzed to investigate the deformation performance of the large span double-row steel sheet piles. A 2D finite-element method was also performed to study the effect of the soil reinforcement technology on deformation control of the double-row steel sheet piles.

Key words: large span double-row steel sheet piles, cofferdam, deformation performance, field observation, finite-element method
