pressure culvert 中文意思是什麼
pressure culvert
解釋
壓力涵洞-
Too much embankment of filled soil will result the destroy of road surface or instability of high - stack soil ; soil pressure at the top of culvert is the key parameter of culvert structure design, more or less of the parameter will result in economic waste or failure of structure
堤頂沉降過大，輕者破壞路面，重者路堤失穩，涵洞頂部土壓力是涵洞結構設計的控制指標，計算過大導致經濟浪費，過小導致涵洞開裂，影響其使用壽命。 -
Brief introduction of engineering case for treatment of bridge and culvert soft foundation with gravel pile and of tunnel soft foundation with high - pressure jet grouting pile
簡單介紹了採用碎石樁進行橋涵軟基處理，採用高壓旋噴樁進行隧道軟基處理的工程實例。 -
Culvert under high - stack soil is a ubiquitous phenomena in road constructions in mountain, self - compression of high - stack soil can not be ignored, soil pressure at the top of culvert is affected by many factors, including the height of high - stack soil, section size of culvert, width of the bottom of valley, grade of valley, property of filled soil, construction procedure and techniques
高路堤下埋設涵洞是山區公路建設的一種較為普遍的現象，高路堤自身壓縮較大，不可忽視，涵洞頂部土壓力的大小又受很多因素的影響，包括填土高度，涵洞截面尺寸，溝谷底部寬度，溝壁坡角，填築體性狀，施工工序與工藝等。 -
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。 -
Based on the concrete engineering of the culvert under the embankment of the high - stacked soil in north second ring highway of guang zhou city, the paper researches the soil pressure distribution and change characteristic through on - the - spot arrangement of the test component
本文依託廣州市北二環高速公路高填土路堤下涵洞的實體工程，通過現場布設測試元件測試，研究了其涵頂土壓力的分佈與變化特徵。 -
On the basis of this, the paper puts forward the effective measure of reducing the vertical soil pressure on the culvert
在此基礎上，提出了減少高填路堤下涵洞結構物上垂直土壓力的有效措施。 -
The paper also adopts elastic - plastic constitutive model and analyzes the soil pressure distribution and settlement performance with the aid of marc program, and contrasts with the test results on the spot, the research results have instructive function to the design and construction of the culvert
藉助marc軟體，採用了彈塑性本構模型，對高填涵洞的土壓力分佈與沉降特徵進行了非線性有限元計算，並與現場實測結果進行對比分析，研究結果對高填路堤下涵洞結構的設計和施工很有指導作用。
