    本文在側限高壓固結儀、常規三軸儀和多功能三軸儀上，分別對原狀飽和結構性k _ 0固結黃土和飽和重塑黃土進行了大量的試驗。通過整理分析各試驗結果，尤其是通過對比飽和重塑黃土的變形和強度特性，得出了飽和結構性k _ 0固結黃土的變形和強度特性。
  3. At the meantime, the rock mass may alternate between loading and unloading and it exists in certain kind of liquid, such as surface water, unconfined water, confined water etc for its intrinsic crannies. the practical rock mass concerned project must solve the key stability pr oblem after the understanding of the complicated mechanical characteristic and the deformation trends to guide the following project design and construction for the demand of security, economy, feasibility and validity. however, the intrinsic nonlinearness and complexity of the engineering rock mass become the main difficulty to predict the stability and deformation, the corresponding structure design must ensure enough safety with all the determinate or random force combination, so a model without the geometry distortion and constitutive equation warp is necessary to be built for the quantificational analysis of practical structure ' s stress, for the simulation of the real process and for the determinate evaluation system and optimization

    由於實際工程巖體其固有的非線性和復雜性，使得求解對應的諸如其穩定性、變形等問題面臨較大的困難，而有關的工程結構的設計必須保證該結構在外來因素的作用下具有足夠的安全度、經濟性和合理性，這必然要求對巖體及其工程結構的受力與變形有一套量化評判體系和優化技術，抓住實際工程問題的本質特徵並建立可行的符合幾何模擬、本構模擬、受力模擬、過程模擬四原則的求解模型，通過該模型的數值模擬成果來指導巖體工程的設計、施工及運營、管理；而巖體結構面的存在使得基於傳統連續介質力學理論的理論分析和數值模擬面臨巨大的挑戰，物理模擬的試驗周期和成本也大大增加，而巖土體工程問題則成為典型的數據有限、了解程度有限類問題，這類問題的解決需要綜合應用理論分析、經驗判斷、物理模擬和數值模擬等方法，數值模擬可以完成目前許多技術手段無法完成的實驗，如參數控制，復雜條件下的邊界條件的處理，同時數值模擬具有高可重復性，且數值模擬的成本和人力開銷等遠低於物理模擬，因此研究巖土體工程問題的流形元數值模擬方法是一項具有理論和實際工程應用價值的重要課題。
