( 2 ) respectively by elastic theory analyses and methods of structural mechanics, transverse static analytical equations for flexible pipeline rigid pipeline are established whose outcomes are applied in numerical example to compare those with that by finite element method. ( 3 ) considering interaction of filled soil, pipeline and foundation, with an eye to non - linear soil model, in view of the initial geo - stress field and the effects of interface between soil and pipeline, and by finite element method the calculational model and method are built for transverse stress in pipeline. then, by the great finite element analytical software ansys, those outcomes are applied in calculation example of positive buried pipe to educe the distribution of circumjacent soil pressure and stresses on cross section and to compare it with that calculated by conventional ways before those outcomes are applied in engineering case of positive buried pipe with flexible filled materials to confirm distribution of soil pressures after the measure for reduction and to compare it with measurements. as a result, the model set up in this paper is proved to be applicable after all above - mentioned analyses
本文基於彈性理論和有限元原理與方法，分析了上埋式地下管道橫向力學計算方法和性狀並探討了上埋式地下管道的減荷等問題： （ 1 ）在分析現有幾種典型的管道垂直土壓力計算方法的基礎上，探討了影響垂直土壓力的主要因素以及改進的方法； （ 2 ）分別通過彈性理論分析法和結構力學的方法，建立了地下管道柔性圓環和剛性管涵的橫向靜力計算方程，並應用在算例中，把所得結果和有限元方法所得結果進行對比分析； （ 3 ）考慮填土、管道和基礎的共同作用、土體的非線性特性、初始應力場以及土體和管道的接觸面因素的影響，利用有限元的思路，建立了地下管道橫向力學有限元計算模型和方法，並且採用大型有限元分析軟體ansys ，針對上埋式管道工程算例，得出了管周土壓力以及管道橫截面應力的分佈狀況和規律，並和理論值進行對比；針對施加柔性填料的上埋式管道工程實例，得出了減荷后的土壓力分佈，並和實測值進行了對比。 -

However, with a reduction in the forecast employment in the central reclamation due to changes in land use assumptions since the second railway development study, and the anticipated opening of shatin to central link ahead of the nil, which would share some of the cross - harbour trips and relieve the nathan road section of twl, it has been decided in early 2003 that the completion of nil would be deferred to beyond 2016
不過，自第二次鐵路發展研究以來，土地用途的假設已有所改變，導致中區填海區的預計就業人口減少。此外，沙田至中環線預計會較北港島線為早通車，之後可分流部分過海乘客，從而紓緩荃灣線彌敦道段的擠塞情況。政府在2003年初決定將北港島線的完成時間押后至2016年以後。 -
