The thesis has summarized the development of the oblique - pull bridge , its construction technology and the importance of bridge construction control , then has introduced project general situation , and has narrated detailed regulation , organization construction , the major work and difficult part of this bridge construction control . the following is the key part of this thesis , firstly , it has introduced the experiment work of early stage , structural calculation and its theoretical result : the absolute altitude of each operating mode , the absolute altitude of building mould in each section and the absolute altitude after pouring concrete ; then , it has discussed the method and content of the line shape control of the main beam , actual absolute altitude of building mould is put forward , and it has described the method of structural stress monitoring , how to arrange measure point and collect data , and how to analyze data . it has also narrated the method of rope force detection and structural temperature inspection 本論文在總結了斜拉橋的發展及其施工工藝,并指出了橋梁施工控制的重要性之后,簡要的介紹了工程概況,敘述了炳草崗金沙江大橋監控細則、組織機構及監控的主要工作和難點部分;論文的核心部分,在介紹了炳草崗金沙江大橋施工控制與監測工作的前期實驗工作和施工各工況標高、各節段支模標高、澆注混凝土后的標高的結構計算和其理論計算結果之后,詳細論述了主梁的標高線形控制方法和內容,實際支模標高的提出,結構應力監控的方法、布點、測讀及其對測讀數據的合理分析方法,索力檢測和結構溫度監測的方法。

Using vb6 programming software , the different marked volume of corresponding absolute altitude for the horizontal vessel which have arbitrary ellipse head and spherical vessel can be calculated more rapidly and accurately , and the method was not restricted by vessel specifications 摘要介紹了利用vb6編程軟件,快速準確地計算出具有任意橢圓形封頭的臥式容器及球罐不同標高液位所對應體積的方法,該方法不受容器規格限制。

The determination of absolute altitudes on the moon meets with difficulties because of the lack of a definite zero reference . 月球上絕對高度的測定因為沒有一個固定的參照零點,頗有困難。
