Influence of Excavation of Complex Foundation Pit on Surrounding Environment
IOP Conference Series: Materials Science and Engineering, 2018 In order to study the deformation of the complex foundation pit, based on an engineering example, the influence of the excavation of foundation pit on adjacent buildings with different supporting structures is analyzed by the finite element software MIDAS GTS/NX especially for the fragile soil. The supporting structure is simplified by the principle of

Advanced Science, EarlyView.Treatment‐resistant wounds caused by polymicrobial biofilms are refractory to conventional therapies due to the dense extracellular matrices. We developed μBLAST, a microblasting wound dressing that combines MnO2‐doped biosilica and a H2O2‐releasing mesh to generate localized oxygen microbubbles that mechanically disrupt biofilms.

Impact of Foundation Pit Excavation upon Metro Tunnel and Viaduct Foundation
Hans Journal of Civil Engineering, 2017 随着城市轨道交通的发展，使得大量基坑工程与地铁结构相邻，由此引起的环境岩土问题日益突出，地铁结构对变形控制要求极其严格，为此，需采取有效措施使基坑施工对地铁结构的影响减小。论文针对广州南沙某邻近地铁四号线由高架转入地下隧道过渡段的基坑设计及施工，应用有限元方法，研究了基坑施工对既有地铁结构的影响，其分析结果可为优化设计和施工提供有益参考，为以后类似的工程实践提供积累经验。 With the development of urban rail transit, which makes lots of foundation pit engineering and metro adjacent structures, the resulting environmental and geotechnical

Finite element analysis of island excavation process of foundation pit
IOP Conference Series: Earth and Environmental Science, 2021 Abstract In the construction of foundation pit, island excavation is suitable for large-scale foundation pit because of its high speed, but it requires a higher support system. In this paper, finite element simulation is carried out for the construction process of island excavation of deep foundation pit with double-ring beam support ...
