为解决目前TBM掘进存在依赖于司机经验,难以对异常情况做出及时响应,导致掘进减缓或刀具磨损加剧的问题,不仅需要在不停机状态下及时准确获取掌子面围岩信息,还要在了解掌子面围岩信息的情况下实现智能辅助决策。依托北疆供水二期工程,分析围岩类别、掘进效能和掘进参数等掘进指标,基于图像识别、数据挖掘和机器学习等技术,通过岩渣图像识别、刀盘振动监测和超前地质预报实现围岩状态的实时感知;构建地质信息、掘进参数、设备与支护参数数据库,进行大数据预处理及关联分析;采用多目标智能优化算法,以掘进速度和刀具寿命为目标,对掘进参数进行优化。在此基础上,提出掘进参数、支护方案、卡机应对措施等辅助决策方法。通过TBM智能辅助掘进技术在XE隧洞试验段中的应用可知,掘进速度总体可提升15.6%,刀具寿命总体提升4.5%,且未发生因掘进参数选择不当导致掘进停滞或设备异常损坏等问题。

目前TBM隧洞设计施工主要采用基于矿山法的围岩分级方法,但由于TBM法与矿山法隧洞施工存在很大差异,传统矿山法的围岩分级方法难以适用于TBM施工。为解决该问题,依托北疆供水二期工程,综合考虑围岩稳定性和围岩可掘性,选取围岩基本质量指标BQ、岩石单轴饱和抗压强度Rc、岩体完整性系数KV和岩石磨蚀性指数CAI作为评价隧洞围岩性质的主要指标,统计18台TBM集群施工收集的近3000组BQ、Rc、KV等岩性指标数据,分析各项岩性指标与纯掘进速度PR及安全系数FS的变化规律,将TBM隧洞围岩分为Ⅰ~Ⅴ级共10个亚级。在此基础上,分析了敞开式TBM的施工特性,进而采用数值模拟方法,对各级围岩在不同支护参数下的稳定性进行对比分析,提出了适用于北疆地区水工隧洞各级围岩的隧洞支护体系及支护参数,共形成7套支护体系设计图,并结合现场实际工程对本文提出的围岩分级支护体系进行验证。现场监测数据表明,本文提出的TBM隧洞围岩分级支护体系有较好的适用性。

西方国家对生态经济研究起步较早,1966年美国经济学家肯尼斯·鲍尔丁在《一门新兴科学--生态经济学》中首次提出了“生态经济学”概念。英国经济学家马歇尔在《经济学原理》一书中提出自然环境的价值对人类经济社会相当重要。美国经济学家布朗认为,生态经济是有利于地球的经济构想,是一种能够维系环境永续不衰的经济,是既能够满足我们需求又不会危及子孙后代满足其自身需求前景的经济。1983年世界环境与发展委员会(WCED)成立,1987年向联合国递交了《我们共同的未来》研究报告,确立了生态经济学理论的地位。

Challenges and Thoughts on Risk Management and Control for the Group Construction of a Super-Long Tunnel by TBM

引用

Engineering 2018年第1期4卷 112-122页

作者： mingjiang deng Xinjiang Association for Science and Technology Urumqi 830011 China

The total length of the second stage of the water supply project in the northern areas of the Xinjiang Uygur Autonomous Region is 540 km, of which the total length of the tunnels is 516 km. The total tun- neling mileage is 569 km, which includes 49 slow-inclined shafts and vertical shafts. Among the tunnels constructed in the project, the Ka-Shuang tunnel, which is a single tunnel with a length of 283 kin, is cur- rently the longest water-conveyance tunnel in the world. The main tunnel of the Ka-Shuang tunnel is divided into 18 tunnel-boring machine （TBM） sections, and 34 drilling-and-blasting sections, with 91 tunnel faces. The construction of the Ka-Shuang tunnel has been regarded as an unprecedented challenge for project construction management, risk control, and safe and efficient construction; it has also pre- sented higher requirements for the design, manufacture, operation, and maintenance of the TBMs and their supporting equipment. Based on the engineering characteristics and adverse geological conditions, it is necessary to analyze the major problems confronted by the construction and systematically locate disaster sources. In addition, the risk level should be reasonably ranked, responsibility should be clearly identified, and a hierarchical-control mechanism should be established. Several techniques are put for- ward in this paper to achieve the objectives mentioned above; these include advanced geological prospecting techniques, intelligent tunneling techniques combined with the sensing and fusion of infor- mation about rock parameters and mechanical parameters, monitoring and early-warning techniques, and modern information technologies. The application of these techniques offers scientific guidance for risk control and puts forward technical ideas about improving the efficiency of safe tunneling. These techniques and ideas have great significance for the development of modern tunneling technolo- gies and research into major construction equipment.

针对干旱地区传统生态调度“只调不灌”造成的湿地生态补水效果欠佳、生境日益退化等实际问题,本文提出了疏漫灌溉的基本理念,明确了疏漫灌溉的定义、内涵及系统组成,搭建了疏漫灌溉系统,构建了疏漫灌溉技术体系。本文以哈巴河流域阿克齐湿地为研究区域,基于疏漫灌溉的系统组成优化了阿克齐湿地原有的工程体系;基于工程布局等要素划分了不同水平年下的三层级生态修复分区;采用Penman-Monteith公式计算了疏漫灌溉区不同地类的适宜生态需水量,采用改进的Tennant法确定了湿地的最低生态流量,最后制定了疏漫灌溉制度。研究结果表明:(1)湿地需水月份集中在4—10月份,其中6—8月份为主要生态需水期,平均生态基流为4.66 m^(3) s;(2)疏漫灌溉工程的布设和生态修复分区的确定改善了湿地供水条件,形成了生态分区与工程体系一一对应的靶向补水模式;(3)疏漫灌溉制度的制订可为生态工程的规划设计以及灌区引水的管理提供科学依据;(4)实施生态调度后,草地、自由水面以及沼泽面积均呈递增趋势,沙化面积减少了9.83%,湿地的水系连通性得到改善,斑块破碎化逐渐修复。研究成果可为提高旱区水资源利用效率、旱区生境的保护与修复提供技术支撑。

Evaluating agricultural water-use efficiency based on water footprint of crop values: a case study in Xinjiang of China

Journal of Arid Land 2020年第4期12卷 580-593页

Efficient agricultural water use is crucial for food safety and water conservation on a global scale. To quantitatively investigate the agricultural water-use efficiency in regions exhibiting the complex agricultural structure, this study developed an indicator named water footprint of crop values(WFV) that is based on the water footprint of crop production. Defined as the water volume used to produce a unit price of crop(m^3/CNY), the new indicator makes it feasible to directly compare the water footprint of different crops from an economic perspective, so as to comprehensively evaluate the water-use efficiency under the complex planting structure. On the basis of WFV, the study further proposed an indicator of structural water-use coefficient(SWUC), which is represented by the ratio of water-use efficiency for a given planting structure to the water efficiency for a reference crop and can quantitatively describe the impact of planting structure on agricultural water efficiency. Then, a case study was implemented in Xinjiang Uygur Autonomous Region of China. The temporal and spatial variations of WFV were assessed for the planting industries in 14 prefectures and cities of Xinjiang between 1991 and 2015. In addition, contribution rate analysis of WFV for different prefectures and cities was conducted to evaluate the variations of WFV caused by different influencing factors: agricultural input, climatic factors, and planting structure. Results from these analyses indicated first that the average WFV of planting industries in Xinjiang significantly decreased from 0.293 m^3/CNY in 1991 to 0.153 m^3/CNY in 2015, corresponding to an average annual change rate of –3.532%. WFV in 13 prefectures and cities(with the exception of Karamay) has declined significantly during the period of 1991–2015, indicating that agricultural water-use efficient has effectively improved. Second, the average SWUC in Xinjiang decreased from 1.17 to 1.08 m^3/CNY in the 1990 s, and then declined

长距离输调水工程是中国新疆地区重要的基础生命线,其长久稳定运行对于促进经济平稳增长和保障居民供水安全至关重要。新疆位居大陆中心,属温带极端大陆性气候,其长距离输调水工程面临严峻的环境挑战。玻璃纤维增强塑料夹砂管(glass fiber reinforced plastic mortar pipes,FRPM)作为长距离输调水工程中重要的水工地下结构用材,凭借其优异的耐化学腐蚀、轻质高强、无二次污染、安装方便、综合造价低等诸多优良特性而被广泛应用于新疆地区。然而,传统FRPM管生成工艺在铺层设计与生产自动化程度方面存在一定局限,导致工程施工过程效率低下;同时,缺少统一的技术标准和设计规范也间接制约了其应用范围。此外,管道工程自动巡检技术与缺陷定量评价标准尚未统一,无法合理量化和准确评价整体工程质量。为此,依托北疆小洼槽供水工程,围绕长距离大口径FRPM管的管材铺层设计与制造工艺、工程设计、质量评定、自动巡检、运行监测与安全保障等关键技术,通过产学研用相结合,持续15年攻关,取得突破性创新成果:①引进吸收并创新了适合于长距离、高工作压力、以连续缠绕工艺为首选的FRPM管生产工艺,优化了大口径FRPM管材铺层设计方法,实现了供料—缠绕—固化—切割—检测全自动化控制,与国外同类产品标准相比,管道挠曲性能和轴向拉伸强度等提高了20%~50%;②提出了安全防护的工程和非工程措施,建立了长距离FRPM管不同缺陷类型危害性等级划分原则,创建了复杂地质条件下长距离FRPM管道工程安全评价理论与方法;③系统揭示了FRPM管质量缺陷产生机理,开发了FRPM管光固化片材局部修复工艺以及内衬聚乙烯(PE)的整体非开挖修复技术,提出了修复效果后评价方法,实现了对长距离FRPM管道工程运行安全的有效掌控。
