钢结构类矩形隧道变形的参数分析

随着经济的发展和城市化的加速,城市空间越来越小,地下隧道的建设已成为建设领域的新方向。传统的双圆隧道占据了大量的地下空间,严重影响了周边的环境,也对居民区产生了极大地破坏。地下隧道通常位于市区,其空间狭小,不便于施工机械与设备的引入和移动。类矩形双道隧道可以解决上述所有问题。矩形盾构隧道占地面积小,可比圆形隧道节省30%-40%的空间。它对环境影响较小,能有效减少对地面的损坏,其单个结构上能容纳双车道,且所需施工时间少,因此它具有较高的经济效益。矩形盾构隧道的隧道断面在组装后基本稳固不动,对周围环境的影响较小,同时可实现长距离弯道。但是,基于对这种钢结构性质的考虑,我们必须分析作用在矩形隧道上的结构应力。本项目以宁波地铁3号线(试验段)为基础,并采用“阳明号”规格为11.83m×7.27m的矩形土压力平衡盾构机。盾构机从陈婆渡南开始一直测量到盾尾,矩形盾构段总长度为429.3m,最小转弯半径为400m,最大纵向坡度为39.5%,最小纵向坡度为2%,隧道最大深度为10.46m,最小深度为2.5米。这的确是隧道行业一场革命,但相关研究却很少,特别是相关英语文献很少(英语迄今为止被认为是科学界的通用语)。本论文中,笔者将分析这种隧道衬砌的结构限制和机械效应。钢铁被认为是建造大跨度结构的重要材料,这就是为什么我们进行这项重要的可行性研究工作时使用钢,而不是复合材料。针对宁波3号线施工隧道断面刚度低,变形大的问题,我们采用PLAXIS软件分析了土与隧道的相互作用,并且确定了是否可以用类矩形钢结构隧道来取代复合材料隧道。值得一提的是,我所研究的这个项目现实中并不存在,因此并没有实际的数据可以与我们的研究进行比较,这对我来说是一个限制,但另一方面,研究这样一个独特的项目也是一件光荣的使命。这篇论文的三个创新点是:1、运用PLAXIS对宁波LIE-3项目进行分析。已经有一些关于这个课题的研究,但是没有一项研究使用岩土工程软件来分析这个项目。2、采用整体钢结构进行隧道施工。这在实际工程中没有得到应用,这样的准矩形隧道还不存在。这项研究提供了一个窥探的可能性领域的情况下,这样的隧道构建。3、进行了参数化研究,并利用实际的土壤数据讨论了隧道厚度和深度对准矩形隧道的影响。

presented an application of using 3 D printing technique for the design and fabrication of a novel fiber Bragg grating( FBG)based sensing platform for foot planar pressure *** sensing unit was fabricated using 3 D printing technique by layering of extruded polylactic acid( PLA) material and mounting FBG sensor at the center of each sensing unit for pressure measurement. Performance of the sensing system was validated by applying load step by step as well as cyclic load on FBG pressure sensors. A simulation study was carried out using the sensing platform to assess foot plantar pressure distribution arises from weight gaining and losing processes of pregnant woman. The monitored four different foot positions such as first metatarsus,second metatarsus,mid-foot and heel exhibited obvious differences during testing process. Foot plantar pressure of heel was 1. 7 times of the pressure occurred at the first and second metatarsus( fore-foot),while there was limited pressure occurred at the mid-foot position during weight gaining process of a female subject. The occurred pressures at the two metatarsus areas were around 90%( pressure ratio) of heel and decreased continuously as the increase of subject weight,but weight losing process had very limited influence on this pressure ratio. Center of gravity of pregnant woman was found to shift backward substantially during the weighting gaining process,leading to a significant rise of the heel pressure. Hence, the protection of the heel position for female is highly important during both pregnancy and after baby delivery.

Habitat utilization and feeding biology of Himalayan Grey Langur （Semnopithecus entellus ajex） were studied from April, 2006 to April, 2007 in Machiara National Park, Azad Jammu and Kashmir, Pakistan. The results showed that in the winter season the most preferred habitat of the langurs was the moist temperate coniferous forests interspersed with deciduous trees, while in the summer season they preferred to migrate into the subalpine scrub forests at higher altitudes. Langurs were folivorous in feeding habit, recorded as consuming more than 49 plant species （27 in summer and 22 in winter） in the study area. The mature leaves （36.12%） were preferred over the young leaves （27.27%） while other food components comprised of fruits （17.00%）, roots （9.45%）, barks （6.69%）, flowers （2.19%） and stems （1.28%） of various plant species.
