Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 1,   Pages 46-60 doi: 10.1007/s11709-020-0676-6

Abstract: This paper reviews the fire problem in critical transportation infrastructures such as bridges and tunnels. The magnitude of the fire problem is illustrated, and the recent increase in fire problems in bridges and tunnels is highlighted. Recent research undertaken to address fire problems in transportation structures is reviewed, as well as critical factors governing the performance of those structures. Furthermore, key strategies recommended for mitigating fire hazards in bridges and tunnels are presented, and their applicability to practical situations is demonstrated through a practical case study. Furthermore, research needs and emerging trends for enhancing the “state-of-the-art” in this area are discussed.

Experimental and modeling studies on installation of arc sprayed Zn anodes for protection of reinforced

Xianming SHI

Frontiers of Structural and Civil Engineering 2016, Volume 10, Issue 1,   Pages 1-11 doi: 10.1007/s11709-016-0312-7

Abstract: Arc sprayed zinc (Zn) anode on concrete surfaces has been an emerging technology for protecting reinforced concrete structures from rebar corrosion in coastal environments. Many cathodic protection (CP) systems with arc sprayed Zn anodes will reach or exceed their design life in the near future and thus may function improperly or insufficiently, making it necessary to replace the aged anodes. However, prior to this study, little was known about the most effective profile for the concrete surface, for either new concrete or old concrete with existing Zn anodes removed. This work develops criteria to properly prepare the concrete surface before the application of new Zn anode. Experimental studies were conducted both in the laboratory and for a field structure in Oregon. Artificial neural network was used to achieve better understanding of the complex cause-and-effect relationships inherent in the Zn-mortar or Zn–concrete systems and was successful in finding meaningful, logical results from the bond strength data. The goal is to achieve strong initial bond strength of new Zn to concrete, which is essential for long-term performance of the CP system. The results from this case study suggest that it is necessary to adjust the anode removal and surface sandblasting based on the electrochemical age of the existing concrete. In all cases of sandblasting, minimize the exposure of large aggregates (e.g., those bigger than 19 mm in diameter).

Geoenvironmental Hazard Risks and Monitoring Technologies for Marine Carbon Sequestration

Zhang Shaopeng, Liu Xiaolei, Cheng Guangwei, Zhu Chaoqi, Li Qingping, He Yufa

Strategic Study of CAE 2023, Volume 25, Issue 3,   Pages 122-130 doi: 10.15302/J-SSCAE-2023.03.011

Abstract:

Marine carbon geological sequestration is crucial for achieving carbon peaking and carbon neutralization in China. However, there exist risks of carbon dioxide (CO2) leakage that leads to seabed geological disasters, severely threatening the safety of marine engineering. Therefore, it is of great practical significance to monitor the environmental geology of sequestration areas. This study briefly introduces several demonstration cases of marine carbon geological sequestration and explores the disaster mechanism associated with CO2 leakage in seabed sequestration areas. It also sorts out the marine environment monitoring technologies in typical CO2 controlled release tests via examples and analyzes the environmental geology monitoring technologies related to CO2 leakage, including seismic investigation and monitoring, resistivity monitoring, gravity monitoring, seabed deformation monitoring, and sediment pore pressure monitoring. Moreover, the prospects of China’s marine carbon geological sequestration and its environmental geology monitoring are presented. We suggest that long-time, low-cost, and real-time monitoring technologies should be developed, a systematic and intelligent multi-dimensional disaster identification model should be established in combination with the baseline investigation of the sequestration areas, and a multi-faceted, multi-level, and multi-disaster monitoring and forecasting system should be built.

Arbuscular mycorrhizal associations and the major regulators

Li XUE, Ertao WANG

Frontiers of Agricultural Science and Engineering 2020, Volume 7, Issue 3,   Pages 296-306 doi: 10.15302/J-FASE-2020347

Abstract:

Plants growing in natural soils encounter diverse biotic and abiotic stresses and have adapted with sophisticated strategies to deal with complex environments such as changing root system structure, evoking biochemical responses and recruiting microbial partners. Under selection pressure, plants and their associated microorganisms assemble into a functional entity known as a holobiont. The commonest cooperative interaction is between plant roots and arbuscular mycorrhizal (AM) fungi. About 80% of terrestrial plants can form AM symbiosis with the ancient phylum Glomeromycota. A very large network of extraradical and intraradical mycelium of AM fungi connects the underground biota and the nearby carbon and nutrient fluxes. Here, we discuss recent progress on the regulators of AM associations with plants, AM fungi and their surrounding environments, and explore further mechanistic insights.
