And the deficiencies are pointed out in present researches, such as highway capacity, level - of - service, influence factor of road alignments, etc. from these, it has confirmed that the thesis should be studied from rational analysis, quantitative analysis of level - of - service, impact on capacity of road alignments, setting - up simulation model, etc. the high - accuracy gps dynamic data acquisition appearance is proposed to be used for the first time to carry on the experiment of overtaking on two - lane highways, and experiment scheme is designed according to the driver ' s perceive to judge each overtaking course. based on the experiment data, it can get two important parameters of acceptant gap ? the critical gap of overtakable time headway and returnable time headway through data processing, which can offer the strong support to the research of two - lane highway capacity with qualitative and quantitative analysis. besides, the experiment methods is provided to observe overtaking ratio and to measure the
研究中首次提出了運用高精度gps動態數據採集儀對雙車道公路上的超車行為進行觀測，設計了根據駕駛員感受度來衡量超車過程的實驗方案，並通過後期數據處理得到了超車過程中兩個重要的可接受間隙參數-可超車車頭時距和可回車車頭時距的臨界間隙值，為定性和定量分析雙車道公路通行能力提供有力的數據支持;同時，還提出了觀測超車率的實驗方法以及測量加速度干擾的實驗方案，統一了計算加速度干擾的時間統計間隔，為雙車道公路的服務水平量化研究奠定基礎;最後還簡單介紹了駕駛員問卷調查法和模擬程序中模型參數標定和驗證的數據採集方法。 -
Through the description of limit equilibrium state and slope stability analysis by strength reduction fem, the safety factor is got, at the same time, the critical failure surface is found automatically. these conclusions testified that this method is practicable if there are detailed investigation, reasonable model and favorable software

Accounting for the effects of imperfection and large displacement of arch, an approach for the stability analysis of arch bridge is presented ， and a program is developed to predict the nonlinear buckling of arch the elastic lateral stability of the jiefang arch bridge in guangzhou during the construction phases and operating periods after its completion is analyzed the results show that the effects of initial deflection and large displacements on the critical load of lateral stability are significant, and that once the initial deflection and large displacement are taken into account, the values of the safety factor are smaller than those obtained by linear buckling analysis
考慮拱肋初始撓度等缺陷的影響，採用桿系結構大位移分析的有限元方法，建立了拱橋非線性穩定的計算方法，並編制了相應的計算程序文中計算了解放大橋鋼管混凝土拱橋在施工階段及成橋后運營期間的彈性側傾穩定結果表明：考慮拱肋初始撓度和結構大位移影響后，拱橋的非線性側傾穩定安全系數比按線性穩定計算值低
