This invention relates to the field of underground structure engineering technology, specifically to an active-passive combined anti-buoyancy system and control method for underground structures. The system includes a pressure sensor array, an adjustable one-way pressure relief valve, and a cloud platform controller. The pressure sensor array is used to periodically collect water pressure data at different locations on the foundation of the underground structure and feed it back to the cloud platform controller. The adjustable one-way pressure relief valve is used to perform drainage operations. The cloud platform controller receives the water pressure data from the pressure sensor array, combines the passive anti-buoyancy bearing capacity of the structure with the buoyancy force experienced by the structure at various locations in the current state, performs a combined anti-buoyancy calculation, obtains the resistance effect ratio within the underground structure range, and controls the opening degree of the adjustable one-way pressure relief valve. This invention can regulate the water pressure level of underground engineering in real time, and by analyzing the structural bearing capacity margin in real time, it can ensure the structural anti-buoyancy safety while reducing drainage volume.

This invention discloses a construction method for a long-span, low-tower cable-stayed bridge. The method involves installing a variable-stiffness temporary consolidation system, including prestressed steel strands and lockable hydraulic damping cylinders, atop the main pier. Controlled-deflection guide plates are installed on the construction formwork. During typhoon warnings, the guide plates are folded to reduce wind resistance. A servo proportional valve is activated to put the lockable hydraulic damping cylinders into a viscous damping state to dissipate vibration energy. The permanent stay cables are asymmetrically tensioned to actively apply compensating bending moments, achieving coordinated wind resistance. During the semi-floating system transition phase, the prestressed steel strands are cut, and the lockable hydraulic damping cylinders are slowly depressurized, allowing the main beam support reaction force to be smoothly transferred to the movable bearings. Before the mid-span closure, the elevation is precisely adjusted using the slight difference in stroke between the lockable hydraulic damping cylinders on both sides of the main pier. This invention effectively counteracts unbalanced bending moments under extreme wind loads, prevents stress damage to the bottom of the main pier, eliminates stress impacts and abrupt changes in alignment during system transition, and achieves precise closure.

This invention discloses a water-damped elastic cable with a check valve-type baffle structure and its installation method, belonging to the field of marine engineering and mooring technology. The water-damped elastic cable with a check valve-type baffle structure and its installation method include a support cylinder, which is formed by a sealed connection of an upper cover, a steel sleeve, and a lower cover to form the cylinder structure.
