打造文化价值工程经验谈

企业之间的最后竞争将是优秀文化理念的角逐。具有恒久价值和社会认可的文化无论从企业内部还是外部，愈来愈超过硬实力的比较作用。一个企业如果缺失自己的文化特色和价值体系，就不会基业常青。因为，没有文化价值的企业解释不了自己的存在，也无法清醒认识、正确判断未来的社会需求和市场竞争趋势。

The Concept and Practice of Treatment for Damage in Railway Tunnel Linings Caused by High-pressure Karst Water北大核心CSCD

In recent years, railway tunnels in karst areas have frequently suffered flooding after high-intensity rainfall, which seriously affects the safety of tunnel operation and the order of transportation, and even interrupts the traffic. Based on the water hazard case in the Yuanbaoshan Tunnel on the Zhijin-Bijie Railway Line, this paper explores the causes of lining damage in terms of geology, rainfall, and the design and construction of water hazard sections, and puts forward the treatment technology for tunnel water hazards with the core concept of "making full use of existing structures and employing open drainage methods in key sections". Besides, this paper simulates and analyzes the formation of hazards and the treatment effect through numerical simulation. The results show that the subjective causes for the damage in tunnel linings include an insufficient understanding of the water-bearing formations at the geological investigation stage, the underestimation of water hazard risks posed by high-intensity rainfall during construction, and the unimproved waterproof and drainage system in the design alteration, while the objective reasons include the development of karst near the tunnel section that passes through the stratum, the strong connectivity of water conduits, and the high-intensity rainfall in a certain period of time on the tunnel site. As for the simulation results, they show that the increase of external water pressure caused by the sudden rise in groundwater level after rainstorm significantly increases the internal force of linings, and eventually leads to a much lower safety factor of sidewall linings and large scale damage, which is in consistency with the characteristics of the actual on-site damage. After on-site emergency treatment, the tunnel structure has become stable and even encountering unprecedentedly heavy rainfall twice, the tunnel has still remained in a good condition. Since then, no water hazards and other disasters have occurred, which proves that the treatment plan is valid. © 2022, Editorial Office of "Modern Tunnelling Technology". All right reserved.     

基于LEAP模型的城市客运交通能耗和污染物排放预测

我国交通运输业能源消耗量与污染物排放量日益增多,交通部门的节能减排措施研究迫在眉睫。本论文基于LEAP模型构建了某城市客运交通能耗与污染物排放模型,并预测了基准情景、政策情景、技术情景及综合情景下该城市客运交通2014-2030年之间的能耗及污染物排放情况。研究表明,三种发展情景下该城市能源需求量及污染物排放较基准情景均有减少,其中综合情景效果最佳,综合情景在2030年的能源消耗与CO2排放可分别减少56.98%和54.55%,CO、HC、NOx与PM2.5可分别减排67.39%、67.27%、51.43%与75.38%。因此应大力发展公共交通,尤其是轨道交通,同时限制私家车的无节制发展,并推广节能环保技术以改善终端利用层次能源结构。     

隧道粉尘颗粒物的危害及控制措施分析

目前我国隧道大规模快速的发展,而钻爆法以其高效、经济的特点在隧道建设过程中起着至关重要的作用。然而,施工期隧道钻孔、爆破、喷射混凝土、出渣等施工工艺都会扬起大量粉尘颗粒物,严重危害现场人员的身体健康,降低施工现场的能见度影响施工效率和安全,同时大量颗粒物加剧机械设备磨损,在一定程度上影响了设备的使用寿命。结合隧道开挖过程,根据粉尘在隧道内分布规律,粉尘产生因素及运移机理,通过比较隧道减尘、降尘、排尘、除尘、阻尘五种控制措施的特点,提出与现场相适应的粉尘颗粒物综合防治措施,从而减小粉尘的危害,提高现场施工环境质量。

Modelling the resilience,friability and costs of an air transport network affected by a large-scale disruptive event

This paper deals with developing a methodology for estimating the resilience, friability, and costs of an air transport network affected by a large-scale disruptive event. The network consists of airports and airspace/air routes between them where airlines operate their flights. Resilience is considered as the ability of the network to neutralize the impacts of disruptive event(s). Friability implies reducing the network’s existing resilience due to removing particular nodes/airports and/or links/air routes, and consequently cancelling the affected airline flights. The costs imply additional expenses imposed on airports, airlines, and air passengers as the potentially most affected actors/stakeholders due to mitigating actions such as delaying, cancelling and rerouting particular affected flights. These actions aim at maintaining both the network’s resilience and safety at the acceptable level under given conditions.Large scale disruptive events, which can compromise the resilience and friability of a given air transport network, include bad weather, failures of particular (crucial) network components, the industrial actions of the air transport staff, natural disasters, terrorist threats/attacks and traffic incidents/accidents.The methodology is applied to the selected real-life case under given conditions. In addition, this methodology could be used for pre-selecting the location of airline hub airport(s), assessing the resilience of planned airline schedules and the prospective consequences, and designing mitigating measures before, during, and in the aftermath of a disruptive event. As such, it could, with slight modifications, be applied to transport networks operated by other transport modes.

高深路堑开挖监控量测施工技术研究

由于高深路堑开挖施工地质复杂,现场机械及人员较多,而有效的监控量测对于调控施工进度,判断边坡的稳定状态以及指导现场施工等发挥着重要作用。为更好的了解边坡动态,更为准确、详细可靠的分析边坡情况,确保施工安全,本文以某公路边坡为工程背景,以现场监控量测为手段,对不同时间、机械开挖不同位置以及降雨前后的边坡进行动态观测。结果表明,位移量随着时间的增长而逐渐减少,反弯点出现后边坡逐渐趋于稳定状态;边坡累计沉降量随开挖深度的增加而不断上升,最后趋于稳定状态。     

灰土挤密桩加固黄土隧道受力与变形性状分析

兰州地区黄土土质疏松、孔隙比大、强度低,普遍具有严重的湿陷性、高压缩性和动力易损性,在增加正压力或孔隙水压力时,极易引起隧道底部及建筑物地基的破坏。为解决兰州绕城高速某大断面黄土隧道底部变形过大的问题,文章选择灰土挤密桩作为加固手段,采用三维数值方法对隧底未处理条件下和采用灰土挤密桩加固后的围岩变形与受力特征进行研究。结果表明:隧底开挖后主要产生隆起,并随开挖方向逐渐增大,起点拱脚处产生下沉,位移最大值出现在隧底中心处;采用灰土挤密桩加固后,其桩身轴力、桩身应力和桩身位移在水平方向均呈现出两边小、中间大的规律,且随开挖方向逐渐增大,桩身承担了隧道开挖产生的大部分荷载,隧底受力与变形均有所减小;灰土挤密桩加固后的隧底位移值减小了32.0%~34.4%,灰土挤密桩能够很好地提高黄土隧道隧底承载力和抵抗变形的能力。
