In this paper, marine environment in Dagukou district of Tianjin port is analyzed and evaluated. Marine oil spill accident is an important source of petroleum hydrocarbon in marine waters. So the simulation and forecasting of influence scope and trajectory of oil spill is a key means to obtain the hazard of oil spill to environmental protection target. A multi-module coupled oil spill model is constructed for simulating the influence scope and trajectory of oil spill, based on the coupling of the hydrodynamic model and wind field data.

Wind Induced Vibration

Abstract In large structures such as towers of suspension bridges or cable-stayed bridges, we often need to suppress the wind-induced vibration for their safety. Especially in the construction stage, the structures are more flexible than the completed ones. This paper discusses the active dampers used to suppress the wind-induced vibration of a tower of a suspension bridge (The Kurushima Bridge 3P Tower) during the construction. The active damper was used to suppress the wind-induced vibration in multiple modes predicted by wind-tunnel test. The controller design of the dampers is based on an H∞ robust control theory. At each erection step, we measured the dynamic properties of the towers to adjust the parameters of the controller using the active dampers as vibration exciters. The measured dynamic properties of the active controlled structures are compared with those of a non-controlled structure. The analysis of free vibration shows the suppression performance of active damper as expected in the controller design.

This article introduced the scheme and method of stress monitoring and cable force monitoring of the central sail in China Navigation Museum. The stress of the important part of steel structure is key indices of the structure safety under construction and using process. By monitoring we can obtain field data to provide basis for the safety assessment and feedback for the future design and construction of similar complex structures.
