Experimental Study on Cyclic Mechanics Characteristic of Saturated Soft Clay Strata

Failure criterion of saturated soft clay is studied under cyclic loads through different experiments. A large number of cyclic torsional shear and cyclic triaxial tests on saturated soft clay under unconsolidated undrained condition are conducted. From the test result analysis, it is seen that the failure of saturated soft clay under static and cyclic loads satisfies Mises criterion. The result from different test stress states is not related to the test stress states or confining pressures. It can be applied in general stress states. Then according to the Mises criterion, the equivalent relationship on failure moment between the test stress state and the general stress state can be established. So the cyclic mechanics characteristics of saturated soft clay at failure moment are clarified in this paper. Furthermore, a theory basis is provided for using pseudo-static elasto-plastic cyclic strength model to evaluate cyclic bearing capacity.     

大学生军事训练安全问题探析

自1985年军训工作开始试点以来,我国大学生的军训工作已经历经三十四年的时光,成就斐然。作为提升国防素质的重要途径,学生军事训练关系我国国防事业的安全与稳定,关系国家的和平与发展。但是近年来,大学生军训过程中的安全问题频发,导致学校小学翼翼、家长担忧无比、社会褒贬不一。在加强学生军事训练的同时,要时刻关注学生的安全,做好军事训练过程中的安全保障工作。
