  1. In education, the author explains that the educational innovation served as premise and security for the development of physics via in - depth analysis on the college education and educational system of physics in germany ; ln philosophy, to avoid the superficial and rigid opinions that philosophy either guides or hinders physics, which is resulted from one - way analysis on the influence of physical knowledge by specific philosophical knowledge, based on the combination of physical achievements by philosophy and profound philosophical knowledge, the author illustrates that the influence on german physics by philosophy reflects more on a kind of spirit a nd this very spirit brings the new quality into the german physics ; in mathematics, by means of analyzing integration of mathematics and physics at different stages, the author is tended to testify that the blooming mathematics in germany is the indispensable condition for the prosperity of german physics because. 2 mathematics provides language tools for the development of physics ; ln culture, by way of analyzing the common features of german physicists and connecting the brilliant german culture, the author audaciously brings forward that the wissenschaft ideas and faust ideas is the important driving force for the prosperity of the development of german physics

    在教育方面,通過對德國大學和物理教育制的形成的分析,說明教育改革是物理學發展的先導和保證;在哲學方面,作者避免了從具哲學知識對物理知識影響的單一方式出發而得出「要麼指導要麼礙」的兩種簡單僵化觀點的弊端,將哲學對物理學成就的影響和德國物理學家很高的哲學素養結合起來分析,說明哲學對德國物理學的作用更多的是現在一種氣質、精神上,正是這種氣質和精神為德國物理學的發展注入了一種新的特質;在數學方面,通過對不同時期數學和物理學融合程度的分析,證明了發達的數學是德國物理學繁榮和領先的必不可少的條件,它為物理學的發展提供了語言工具;文化方面,通過對物理學家特點的分析聯系燦爛的德國文化,作者大膽提出其中蘊涵的wissenschaft思想和浮士德精神是德國物理學繁榮和領先的重要動

    摘要將飽水軟土地基視為兩相介質,考慮水的滲流和土骨架變形的耦合作用,用間接邊界元法分析層狀飽水軟土地基中橫向受荷樁動抗,探討飽和土中孔隙流對飽和土中橫向受荷樁動抗的影響。
  4. Based on the formula which is used to compute the lateral resistance of single pile deduced by wang qitong, a formula is setup whose precondition is that the pile and the lateral soil directly around the pile deform in - phase. on the basis of that the contact stress of the foundation is equal, a formula that can be used to conform the stress - ratio of the composite ground is set up, on the same time, the principles of the deformation harmony of the soil and the piles in the composite ground are also discussed. combining with results of this test, a formula which can calculate the bearing capacity that considering the effect of group piles of the composite ground is also deduced

    視攪拌樁樁為均質彈性介質,推導了復合地基中單樁有效樁長的理論計算公式;根據王啟銅柔性樁樁側摩計算公式,以樁側土與樁協調位移為前提推導了柔性樁樁側摩的計算公式;以基底接觸應均勻分佈,樁、樁間土均質為前提,討論了樁,土協同工作原理,從而得出復合地基樁、土荷載變形特性,以及樁、土應比計算公式;結合本次試驗,通過計算加載時樁與土的荷載分擔情況以及在極限狀態下樁土承載發揮值,提出考慮樁效應的攪拌樁復合地基承載計算公式。
