  1. At present plenty of experimental study has been made on the materials and structural performance of asphalt concrete cores in the world, and the design methods and construction technique as well as equipments have been more mature. however, there is still lack of the research of its basic performance. in this thesis, in combination with the actual project, the experimental study has been employed with the field core specimen and the specimen made in laboratory, mainly include the static triaxial test, confinement pressure stabilization test and stress relaxation test

    目前，國內外對瀝青混凝土心墻的材料和結構性能已進行了一些試驗研究，其設計方法、施工工藝和設備較為成熟，但其基本性能研究方面顯得較為薄弱，本文結合實際工程對瀝青混凝土心墻的芯樣和試驗室成型的試件進行了試驗研究，主要包括靜三軸試驗、圍壓穩定試驗以及應力鬆弛試驗研究，得到以下基本結論： 1
  2. By altering the length of some structural members while keeping the prestress level above a given lower bound without relaxation, the nodal displacements of prestressed cable structure are controlled

    在保證預應力索結構各索段一定的預應力水平且不致鬆弛的情況下，通過改變結構中某些索段的長度，來達到控制節點位移的目的。
  3. We have deduced mathematical equations modeling its vibration and studied the stability of the semigroup associated with the equation system. we obtain the exponential stability under certain hypotheses of smoothness and structural condition of the coefficients of the system, applying the relaxation function decays exponentially. this result does not need the continuity of the damping coefficient at the interface

    對于具有局部粘彈性阻尼的高維波方程的能量的指數衰減問題， liuetal . 51 }和riveraetal . 63分別對k一v型和boltzmann型的情形進行了研究，在假設了阻尼系數是光滑的並且附加了一些結構性條件的情形下，得到了指數穩定性的結果。
  4. Involving interaction of gasket, bolts and flange rings, the load - deformation and the structural fuzzy reliability of each component are analyzed in the case of ideality, external loads and creep - relaxation respectively. and then, the sealing fuzzy reliability of the flanged connection system is researched. the function of each part of genetic algorithm is analyzed in application to nonlinear unconstrained and constrained optimization
