Look back generally to elaborate the development and present situation of the stress - strain model of soil. according to a great deal of data of the test and research of zipingpu reservoir concrete faced rockfill dam ' s material, suggest the more reasonable stress - strain - volume change equation to contain strain softening, dilatancy ( shrinkage ) of the no viscous moraine and gravel. suggest the method to gain the model ' s parameter
較全面回顧闡述了土體本構模型的發展和現狀，根據紫坪鋪面板堆石壩築壩料的大量試驗研究，提出相對合理的應力應變關系方程，以反映土體的應變軟化、剪脹性，並提出模型參數的求取方法，求取模型參數。 -
The basic physical and mechanical properties, mineral composition, micro structures, swelling potential, consolidated drained triaxial shear strength, parameters of constitutive model and residual strength of the soft clayey rocks were tested in laboratory with a large number of natural samples. the changing trend of the strength about these rocks is obtained by modeling the condition of softening due to immersion. from the principles of modern soil mechanics, the structural and swelling characteristics of soft clayey rocks were analyzed systematically
本文通過現場調查，查明風化泥質軟巖的宏觀結構特徵，利用現代試驗測試手段，取原狀土系統進行特殊土室內土工試驗，測定土的基本物理力學特性、礦物成分及微觀結構、膨脹性、三軸排水剪強度及本構模型參數、軟化殘余強度，並模擬土體在長期浸水軟化后的強度變化趨勢，測試該類土的浸水軟化殘余強度。 -
In view of the technical problems of softening of foundation soil and reduction of bearing capacity of the breakwater under the action of repeated wave loads during the execution of the second phase of the deepwater waterway regulation project in the changjiang estuary, tianjin port construction corporation has successfully developed safer, higher quality and highly efficient technology and special - purpose marine craft and machinery for laying deepwater sand blankets and offshore installation of prefabricated drains, which were more suitable for the working conditions in the changjiang estuary, and has also explored the construction technology for prefabrication of caissons with rubber anti - sliding plates, to ensure the efficient implementation of the engineering measures against softening of foundation soil
