工程建设, 2023 随着我国经济发展和科技水平进步，大跨度悬挑钢结构被广泛应用于各种大型公共建筑。由于大跨度悬挑钢结构形式具有复杂性、多样性等特点，要求钢结构安装技术更加先进、施工顺序安排更加合理。国内针对大跨度、大空间的钢结构施工进行了丰富的研究，如国家体育场钢结构施工中采用模拟分析的方法对关键构件的调整，加快了施工进度，降低了用钢量，并提出了钢结构施工要点；崔晓强等对大跨度钢结构施工过程的结构分析方法进行了研究，提出了利用有限元软件对施工全过程跟踪的方法；刘勇庆对大悬挑悬挂结构施工过程进行的模拟分析，通过模拟数据的分析，

城市建设理论研究—市政工程, 2022 论文结合中国南昌市地铁4号线工程，利用Plaxis 3D软件对盾构隧道施工下穿建筑物进行模拟，研究盾构掘进过程对桩基沉降的影响，利用数值模拟重点分析了开挖顺序和开挖速度对桩基的位移情况影响。研究结果表明，开挖速度对桩基沉降有较大影响，在开挖面经过桩基后，开挖速度越快，桩基的沉降越小；但如果开挖速度继续增大，开挖速度对桩基沉降的影响下将显著减小。由于双线隧道错开施工时，对周围土体有一个二次扰动的作用，双线隧道同步施工时桩基的沉降明显小于双线隧道分步开挖时的情况并对设计方案进行安全评估 ...

Conservation Biology, Volume 37, Issue 2, April 2023., 2023 Abstract Managed breeding programs are an important tool in marsupial conservation efforts but may be costly and have adverse genetic effects in unavoidably small captive colonies. Biobanking and assisted reproductive technologies (ARTs) could help overcome these challenges, but further demonstration of their potential is required to improve uptake. We

Conservation Biology, Volume 36, Issue 6, December 2022., 2022 Abstract Development and implementation of effective protected area management to reduce deforestation depend in part on identifying factors contributing to forest loss and areas at risk of conversion, but standard land‐use‐change modeling may not fully capture contextual factors that are not easily quantified.

Conservation Biology, Volume 36, Issue 6, December 2022., 2022 Abstract Africa's protected areas (PAs) are the last stronghold of the continent's unique biodiversity, but they appear increasingly threatened by climate change, substantial human population growth, and land‐use change. Conservation planning is challenged by uncertainty about how strongly and where these drivers will interact over the next few decades.

Ecological and economic implications of alternative metrics in biodiversity offset markets
Conservation Biology, Volume 36, Issue 5, October 2022., 2022 Abstract Policy tools are needed that allow reconciliation of human development pressures with conservation priorities. Biodiversity offsetting can be used to compensate for ecological losses caused by development activities. Landowners can choose to undertake conservation actions, including habitat restoration, to generate biodiversity offsets ...

Understanding and minimizing environmental impacts of the Belt and Road Initiative
Conservation Biology, Volume 33, Issue 4, Page 883-894, August 2019., 2019 Abstract China's Belt and Road Initiative (BRI) sets to create connections and build infrastructure across Eurasia, Asia, and parts of the African continent in its initial phase and is the largest infrastructure project of all time. Any infrastructure project on this scale will necessarily pass through ecofragile regions and key biodiversity areas ...

Detecting deterrence from patrol data
Conservation Biology, Volume 33, Issue 3, Page 665-675, June 2019., 2019 Abstract The threat posed to protected areas by the illegal killing of wildlife is countered principally by ranger patrols that aim to detect and deter potential offenders. Deterring poaching is a fundamental conservation objective, but its achievement is difficult to identify, especially when the prime source of information comes in the form of the ...
