The pile foundation cutting and underpinning process during shield tunnelling significantly impacts the stability of bridge substructures. In this paper, tunnel area from Hongguzhong Avenue Station to Yangming Park Nanchang Metro Line 2 was taken as research subject, which crosses project south approach section Bayi Bridge. Through numerical simulation on-site monitoring analysis, influence act...

During the construction period of sea-crossing bridge, pile foundation and other operations are easy to cause marine water environment pollution. In order enhance green development level cross-river (sea) channel project, this paper selects Shenzhen-Zhongshan Link, a typical cross-sea traffic cluster as research object. And introduces environmental protection technologies such bored with steel ...

Platform-pile systems are typically used in bridge foundations and seaport structures. These difficult to analyze using a conventional low-strain integrity test (LST) due periodic oscillations. A staggered-grid finite-difference (SFD) method is proposed for platform-pile system soil verified with ABAQUS measured data. Different impact locations on the top surface of platform lateral pile analyz...

This research is to assess the influences of inertial mass from girder on dynamic characteristic, response, and structure-soil interaction a pile-soil-pier subsystem in scale-model cable-stayed bridge. Therefore, both connection configurations between girder, including sliding fixed connections, were designed present various superstructure delivered pile-soil-pier. The supported by 3 × pile-gro...
