The Loess Plateau is the core area in the Yellow River basin for implementing environmental protection and high-quality development strategies. A series of ecological projects has implemented aimed at soil and water conservation and ecological management on the Loess Plateau over the past 70 years. The effects of the ecological projects are apparent mainly through a marked increase in vegetation cover, controlled soil erosion and reduced flow of sediment into the Yellow River, continual optimization of the industrial structure and increased production from arable land, poverty alleviation and greater prosperity, and optimal allocation of space for biological organisms. Major problems have also been analyzed in ecological management including the fragile ecosystem of the region, maintaining the stability of vegetation, lower agricultural productivity and continued risk from natural disasters. Some suitable schemes and models have been developed for the coordinated development of the region through research and demonstration, striking the optimum balance between rural industry and ecology, and increased regional capacity to supply high-quality ecological products. Countermeasures to address the problems are suggested to guide ecological management and high-quality development in the future.

针对海上风力机塔柱支撑结构受到土基、海洋流体作用的复杂特点,开展多介质耦合条件下塔柱支撑结构动力特性研究。在考虑流固耦合基础上,进一步考虑海床土基弹性条件对塔柱结构动力特性的影响。最后得出了水流、土基与塔柱结构三合一综合动力特性分析结果,初步取得了变化规律。研究结果对海上风电场塔架支撑结构的抗振设计及进一步的研究提供了重要基础性参考依据。

近20年能源结构调整使我国土壤多环芳烃浓度下降 Article

近几十年来,我国在快速发展和工业化的同时,在环境污染防治方面也做出了巨大努力。然而,这些全国性措施(如能源结构调整)对土壤中污染物浓度的影响尚未得到很好的量化。多环芳烃(PAHs)污染在全球范围内引发重要关注,且PAHs排放与能源结构有关。因此,我们推测我国能源结构的调整可能会降低土壤中PAHs的含量。为了验证这一假设,我们于2008 年和2019 年在北京54 个点位重复采集了土壤样品,分析了美国环境保护署(US EPA)提出的16 种优控PAHs 化合物(Σ16PAHs)的浓度,并收集了过去20 年全国1704 个土壤采样点的数据。结果表明,我国Σ16PAHs浓度沿城市-郊区-农村-背景点梯度下降,且Σ16PAHs 浓度与区域总产值(GRP)有关,在GRP 较低时Σ16PAHs 浓度随GRP 的增加而增加,随后在GRP 达到一定水平时趋于平稳。过去20 年,我国土壤Σ16PAHs 的平均浓度呈下降趋势,其中北京土壤Σ16PAHs的平均浓度从2008 年的22.7 μg⋅g‒1总有机碳(TOC)显著下降到2019 年的10.0 μg⋅g‒1 TOC。源识别分析推断,土壤PAHs浓度的下降趋势是由于我国煤炭、焦炭、部分油类消费量下降以及电力、天然气等清洁能源消费量上升所致。本研究例证了调整能源结构在降低土壤多环芳烃浓度和改善土壤环境质量中的重要作用。

装配式结构与传统的现浇结构相比具有节能、环保、节省模具、工期较短等特点,已在地上建筑中获得了飞速发展。由于地下环境复杂,地下装配式结构接头部位的防水处理成为难题,因此,地下装配式结构近几年在我国才刚刚起步。本文在分析地下装配式结构的接头形式和防水技术现状的基础上,提出了应用环氧灌浆料对预制装配式结构接头进行灌封,通过试验研究了环氧灌浆料本身及其黏接混凝土的力学性能。同时还针对明挖法修建的技术特点,介绍了基坑肥槽预拌固化土回填技术,阐述了预拌固化土对地下工程结构防水的作用,研究成果可供类似工程参考。
