许多新成土有一层淡薄表层，有些则有一层人为扰动层。 - The ecosystem health of wetland is that substance recycle and energy flow are not destroyed , elasticity and stability are retained ; system can fight against disturbance of nature and people , function of which is various
湿地生态系统健康是指系统内部的物质循环和能量流动保持正常状态，系统对长期或突发的自然或人为扰动能保持弹性和稳定性，整体功能表现出多样性。 - Considering these two difficulties , people often separate the two levels of the design of the retaining and protecting engineering for simplicity in practice . therefore , there exist lots of vestiges of artificial interference in the optimization desig n of the retaining and protecting engineering
正因如此，在实际基坑工程实践中，人们往往将基坑支护设计的两个层次割裂开来以简化设计，从而在基坑支护优化设计中留下了大量的人为扰动“痕迹” 。 - The ecological study of macrofauna was conducted on four typical sampling stations selected in the northern muddy bottom area of jiaozhou bay , estuary of dagu river , culturing and nearby area in hangdao in mar . , jun . , aug . and dec . , 2002 . abundance and biomass of macrofauna were investigated by quantitative study . the macrobenthic community structure and biodiversity were analyzed through multivariate statistic analysis
本研究分别在胶州湾北部软底区、大沽河口、黄岛养殖区及养殖区邻域选取四个典型站位，于2002年3月、 6月、 8月和12月野外采样，对大型底栖动物进行了定量研究，采用多元统计方法分析了群落结构和生物多样性，探讨了底栖生物群落与环境因子的关系；用丰度和生物量比较曲线法分析大型底栖生物群落对自然和人为扰动产生的响应。 - In this paper , the finite - element numerical analysis calculation is applied to the foundation of high - rise and multi - floor building and the evolvement law of stress and displacement of tunnel used by urban traffic to explore the mutual influence between the wall rock of underground space and high - rise building foundation , taking account of the specific construction situation in the " sanmu garden " project in dadukou district in chongqing , from the perspective of underground space static - force structure stability analysis to open a underground tunnel with 6m in span and 7 . 5m in height for track traffic 20m below the surface . this paper , taking considerations of three different states , i . e . the natural state without any artificial interference , the state of high - rise buildings on the surface , and the underground tunnel state with excavation for track traffic , and four plane lines and four vertical lines , analyzes and studies the distributing law of stress and displacement of calculation section from the following aspects : ( 1 ) the main stress vectorgraph , displacement distribution graph ( ux , uy ) and chromatogram graph of stress isoline ( 1 , 2 , xy ) of section under different states ; ( 2 ) the contrastive distribution curve of stress ( 1 , 2 , xy ) of different plane and vertical lines under the same state ; ( 3 ) the contrastive distribution curve of stress ( 1 , 2 , xy ) of the same plane and vertical lines under different states , wishing to provide references for underground space utilization and project designing and construction of the tunnel under high - rise buildings in the future
本文结合重庆市大渡口区“三木花园”开发建设项目，从地下空间静力结构稳定性分析角度出发，针对在该项目中涉及的高层和多层建筑物以及在其地下20米处开挖了一个用于轨道交通的跨度6米，高7 . 5米的地下隧道这一具体工程情况，采用2d - 3d -有限元结构分析程序对高层与多层建筑物的地基基础及其与城市轨道交通使用的地下隧道围岩的应力与位移演变规律进行了有限元数值分析计算，探索了地下空间围岩与高层或多层建筑物地基基础之间的相互影响，通过考虑未受到任何人为扰动影响的天然状态、地表存在多层或高层建筑物状态和地下开挖用于轨道交通的地下隧道状态等三种不同状态以及4个水平剖线和4个垂直剖线等不同情况，从以下几个方面具体分析研究了计算断面的应力与位移分布规律： ( 1 )在各种不同状态下计算断面的主应力矢量图、位移分布图( ux 、 uy )以及应力等值线色谱图( _ 1 、 _ 2 、 _ ( xy ) )等； ( 2 )相同状态下不同水平与垂直剖线的应力_ 1 、 _ 2和_ ( xy )对比分布曲线； ( 3 )不同状态下相同水平或垂直剖线的应力_ 1 、 _ 2和_ ( xy )的对比分布曲线等，为今后在对地下空间的开发利用以及在高层建筑物地下开挖硐室时的工程设计和工程施工提供参考依据。
