    (五)研究了基坑形狀、面積、深度與深基坑降水相關性,給出了計算基坑至承壓含水層間的最小距離公式,分析了對不同基坑應採用的降水方法。
  2. The contents include : based on the previous research and the data of experimentations, the author researches and develops a kind of satisfactory semi - empirical formula of nonlinear temperature distribution, and calculates the temperature stress of rigid - framed arch bridge by the fem. the temperature effects of bridge structure by annual and sunlight temperature difference are discussed, it indicates that the temperature effect of annual temperature difference is small but the temperature effect of sunlight temperature difference is great and the temperature stress along beam depth resulted from sunlight temperature difference is nonlinear. with the comparison between the temperature effects of different position of bridge, the results show that where the section of bridge is small, the temperature stress of it is large

    本文主要包括以下內容:從理論上研究並結合實測資料發展了一種比較理想的半經驗溫度場非線性分佈公式,並將有限元方法應用於剛架拱橋結構溫度應力的計算中,對橋梁結構進行整體溫度應力分析;討論了年溫差和日照溫差引起的橋梁結構的溫度效應,表明年溫差引起的溫度效應較小,而日照溫差引起的溫度應力較大且沿梁高呈非線性分佈;分析比較了橋梁結構各個部位的溫度效應的大小,可知截面越小溫度拉應力越大,受力越不利;並對箱梁結構由於構造不同引起的縱向與橫向的溫度效應大小進行了探討,發現在下緣也會出現相當大的溫度拉應力,並且梗腋的存在反而增加了部的溫度拉應力;還對幾種相近的剛構式橋型的溫度效應進行了分析對比,總結了這些橋型對溫度效應的優劣,並提出相應的對性措施。
  3.
