    摘要: The present invention of damping segmental ring structure for subway tunnels built in grim environments of deformable ground can mitigate the stress-concentration of the tunnel lining structures. The deformable ground can be caused by differential settlement or high-intensity earthquakes. Embodiments of the invention have self-adjustment features and forms for deformation and rotation, which comprise one adapter in the middle, two transitional grooved segmental structures, and an internal steel tube. All three forms comprised 3 or 4 pieces with the same features so they can be easily installed, transported and erected on sites and bolts are used to bolt them together to form an integrity structure with damping characteristics. The damper placed in the middle comprises two loading plates that form the shell of the damper, the internal core of the damper which includes interbedded installed rubber pads and steel plates within the loading plates and spring systems that compress the internal core. The springs are locked to the loading plates using locking clamps and the loading plates are bolted to the transitional grooved segmental ring structures, and the transitional grooved segmental ring structures are bolted themselves in the circumferential direction to form a ring structure and bolted with the regular segmental ring structures in the longitudinal direction. The internal steel tube is concentric with the damper but has a smaller diameter so it can support the damper by fastening the counter-reaction bolts installed in the bent-up flanges of each piece. Waterproof anti-slippery rubber pads are placed in all interfaces between the damper, and the transitional segmental ring structure, the regular segmental ring structure and the internal steel tube. The invention of the damping segmental ring structure has self-adjustment capabilities for deformation and rotation whereas the stiffness remains sufficient to resist soil and groundwater pressure. The invented damping segmental ring structure can be manufactured in factories that manufacture the regular segmental ring structure and can be shipped to and installed on-site using the same equipment that installs the regular segmental ring structure. The internal steel tube provides double-safety for the stiffness of the damper and the supports can be adjusted during tunnel operations.

    摘要: Embodiments of the present foundation for wind turbine generators comprise four structural members: a relatively long central hollow pier, several arm grade beams, a continued grade beam and a continued shear key. The central hollow pier positions in the center of the foundation system, arm grade beams are arranged evenly in radial direction and extend from the pier to the continued grade beam. Continued grade beam is arranged circumferentially in outer periphery and the continued shear key is built below it. Arm grade beams have a varied section with the far end embedding into ground. The top of the continued grade beam matches the top of arm grade beams, while the continued shear key embeds deeper into ground. All structural members are constructed of cast-in-place concrete reinforced with rebars, and all connections are fixed and rigid. The present foundation uses the ground to shape and form the structural members, no formwork, backfilling and compaction is needed.

    摘要: Embodiments of the present foundation for wind turbine generators comprise four structural members: one short central hollow pier, one continued grade beam, several solid piles built below the continued grade beam, and several arm grade beams linking the structural members. All structural members are constructed of cast-in-place concrete reinforced with rebars, and all connections are fixed and rigid. The short central hollow pier positions in the center of the system, functions as a hub to take the loadings and continuously to transfer and distribute the loadings further to the continued grade beam, arranged circumferentially in outer periphery of the system, and deeper to the solid piles, through the arm grade beams, which have a varied section and embed into ground in the far end. The present foundation utilizes the ground to shape and form the structural members, no formworks, backfilling and compaction is needed.
