An automated and rapid measuring method for cross-section deformation of shield tunnels
Abstract: Due to the high cost and continuously aging deterioration, the inspection and maintenance of structures have become increasingly important in the tunneling field over the past decades [1]. Shield tunnel consists of precast concrete segments that form rings by the connection of steel bolts. Unlike tunnel constructed by cast-on-site concrete linings, the rigidity of shield tunnel is relatively...

Interlaid rock wall excavation method and use of information technology for construction of a shallow subway station...
Abstract: The Wulukou station of Chongqing subway No.6 is located in the old pedestrian streetwith soft surrounding rock mass. Its crossing section is 326m, span is 20.59m, and the minimum of buried depth is only 4 m. A new subsurface construction method named as “interlaid rock wall” was especially proposed. The information technology was simultaneously introduced for assessing the stability of station...

Uneven settlement induced by a curved shielding tube
Abstract: Settlement induced by a curved tube is different from that in straight tube case. The field test on a metro project in Malaysia has been conducted,which contains several curve portions. Five observation sections at varing alignment radius are arranged.The in-site surface settlements on those sections are well fitted by two separate Peck formulas with the tube centerline as the axis.And the...
