英文
uniformly varying load-
The collapsible loess is often met during the construction of the high - grade highway in the loess area, and the main failure is the uneven subsidence of the roadbed and the culvert, which affects the safe usage of the roadbed and the culvert, etc. directed against this, based on the chankou - lanzhou freeway construction, the paper analyzes the application of the composite ground formed by lime - soil pile under the bridge and designs the project, discusses the rules of the contact pressure, the stress ratio of the pile and the soil, compares the p - s curves of one pile, the composite ground formed by one pile and the composite ground formed by two piles based on the in - situ plate loading test, evaluates the bearing capacity of the composite ground of the project
黃土地區的高等級公路建設中經常遇到濕陷性黃土問題，其病害類型主要是地基土受水浸濕后引起路基、橋臺、涵洞等的不均勻沉降，直接影響路基、構造物等的正常使用。針對此問題，本文依託甘肅讒口至蘭州柳溝河高速公路建設工程，對橋基灰土樁復合地基應用的可行性進行了深入分析，根據具體工程進行了合理的設計與計算，並配合現場靜載荷試驗及壓力盒實測數據，探討了基底應力分佈規律，樁土應力比，變形模量的變化關系，對比分析了單樁、單樁復合和雙樁復合的p ? s關系，對橋基灰土樁復合地基承載力進行了整體評價。In this thesis, the experimental research of the behavior of high strength concrete axial compression columns and eccentric compression columns under non - uniform temperature field are conducted. from the experimental analysis, the variational regularity of ultimate load capacity and deformation of high strength concrete compression - flexure members under non - uniform temperature field is obtained. the influences of different factors including temperature, stirrup contents, strength grade of concrete, pre - loading level, eccentricity and different loading - temperature paths to refractory capability of members are investigated
文中還對高強混凝土軸心受壓柱和偏心受壓柱在不均勻溫度場下的力學性能進行了試驗研究，通過試驗分析了高強混凝土壓彎構件極限承載力和變形在不均勻溫度場下的變化規律，考察了不同升溫溫度、箍筋用量、混凝土強度等級、預加荷載水平、荷載偏心以及荷載?溫度途徑等對構件耐火性能的影響，通過試驗量測，得到了構件的截面溫度場。
