Test on Muddy Soil Reinforcement by Negative Pressure and Electro-Osmosis Inside Cover-Bearing-Type Bucket Foundation for Offshore Wind Turbines

Cover-bearing-type bucket foundation for offshore wind turbines has been paid more and more attention due to its low cost and great bearing capacity. In order to ensure the cover-bearing mode, the muddy soil inside the bucket foundation should be reinforced by some soil consolidation methods, such as negative pressure and electro-osmosis. Firstly, tests were conducted to obtain the reasonable current density. Meanwhile, to improve the electro-osmotic speed and effectiveness, other factors such as intermittent power and layout of electrode, were also studied in the tests. Then, the soil reinforcing tests by negative pressure combined with electro-osmosis were performed for the muddy soil consolidation inside the bucket foundation. The results showed that soil reinforcement by negative pressure was quicker and more obvious during the early phase, and electro-osmotic method can affect more range of soil by rational arrangement of electrodes. Compared with negative pressure, the electro-osmotic method was a continuous and relatively slow process of reinforcement, which was complementary to the negative pressure method. The voltage value of electro-osmosis had little effect on the muddy soil reinforcement inside the bucket foundation, and 1.5 A was chosen as the most reasonable current value for scale model testing in the electro-osmotic method.

地铁工程地层预加固部位识别系统研究

鉴于地铁工程地层预加固技术没有系统性规范，对地层预加固部位与加固方法缺乏统一认识。尤其，在地层预加固部位及其风险的认识方面还主要停留在主观判断上。通过识别出为保证工程自身安全与环境安全，需要对地层采取预加固措施的相关影响因素，进而应用风险管理理论对这些影响因素进行模糊综合评价，从而确定地铁工程中的地层预加固部位及其加固方法。这个识别、分析、评价、处理的过程，也就是建立地铁工程地层预加固部位识别系统的过程，系统的建立可以为采用计算机编制程序软件进行定量评价提供理论依据与方法指导。
